Omnia i900 with no 3g?

I just bought a singapore-configured omnia and i can only get it to connect to edge here despite being in a known 3g network... In the connection manager i only have options for "cellular line" and "cellular line (gprs)" (as well as haynes and bluetooth etc), but no "cellular line (gprs, 3g)" as I do on my other phone...
Any suggestions as to how i might get it to recognize the 3g in my area? (rogers/at&t).
Thanks!

if i'm not mistaken i900 has 3G but only in the 2100 band, maybe you can check with your operator what 3G band they are using...

I believe rogers runs their 3g on 1900 and there is no option for 2100 on the phone, only 850/1900 and 900/1800...

what you are saying is the GSM band, what I meant was the UMTS band which is 2100 for the i780

I have no option for UMTS in the phone ;\ I believe rogers runs on 2100 also but i'd have to check my other phone... is there somewhere where 3g/umts could be disabled on the phone? The specs say that it supports tri-band and umts.
edit: just checked the rogers phone, under settings -> phone i have a seperate tab for "band" wherein i can choose the gms/umts band "gsm(900+1800)+umts(2100)" etc but on the omnia there is nothing of the sort.
is it possible that the korean version of the phone somehow has umts disabled?

This is a big mystery to which there is no real answer.
I have a I900 as well, but I do not have 3G/WCDMA in the US via AT&T which uses 850/1900 bands (which I believe is what Rogers and Fido use).
Here are some interesting bits:
- The I907 is a North American version that supports 3G on 850 and 1900.
- No one to my knowledge has seen any different hardware parts related to the Cell in the I907 vs the I900. The radio in both supports 8 of the UMTS bands that have been proposed (only 4 are in common use, and one of those is only in Japan). The cell antenae of the I900 are designed for optimal gain in the 850/1900 bands.
The Radio is idential to that of the Diamond, Touch Pro, G1, Kaiser, Touch, Touch HD and anything else using the 7201A or 7200 chipset. The I900 and I907 do not use this chipset, but it uses the same radio hardware.
No one was able to get the EU Diamond to use the 850/1900 GSM band, and in fact the US Diamond has the same radio Firmware as the EU diamond.
I was confident that if anyone could figure out how to make this work, it would be people at XDA on an HTC device (caveat - there are a lot of europeans here who don't care about 3G in north America, so I may have been wrong there)
Where does it say tri band UMTS on your phone?

I just upped the UK t-mobile rom into the phone and surprise, the profiles for singapore internet are still in the phone... HOW is this possible on a full rom (pda + phone) flash???
anyways, looks like the umts spectrums we use are locked in the firmware for the phone, despite the radio being able to use it ;\

Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.

There are many Roms Available on Modaco
www.
It seems like there are at least four places in which firmware lives:
- "Phone" (usually called Radio)
- "PDA" (the rest of the ROM)
- "CSC" (seems to be for branding. I.e. TMobile has a special .csc file as compared to stock ROMS with similar firmware)
- GSM settings, accessible through dialing obscure number on the Phone. Search Modaco for a list, people seem to find new ones every day. Some of these numbers just effect the ROM settings, but some seems a little more powerful.
- In some of the recent Roms there is a Band Tab in the phone settings, but it only lists "Auto", "850/1900", "900/1800" and "WCDMA". WCDMA is 2100 in the rom I have installed (Signapore PDA with an "Open Market" Phone (XXHI2) )

mine, with the t-mobile rom, only shows 800/1900 as an option in band selection ;\

Diamond is not working in usa !!!!!!!!!!! Help

The diamond with what ROM or Radio ever , shows the freaking US Nonstandard Standard of 850 and 1900 mhz for UMTS
But to use it for online purpose is impossible. It goes only to Edge what is closer to the speed of smokesigns .
The old touch cruise does well in the same areas with the same provider and the same settings .
Someone here who live also in the (Telephone development country) USA and figured out any solution ?
Thanks a lot
i do not have the international Version of the Diamond

sounds like you have the European (900+2100) diamond that does not have the us 3G (850+1900) bands. if this is the case you are stuck with EDGE.

it is true
but the radio or HTC ROM shows 850/1900 UMTS is this just another joke from HTC ?
Thanks

some roms show all the radio versions but are not usable because of hardware dependencies. my rom shows the china 1700 umts band but i know the hardware in my phone does not support it.
it's not htc but rather rom cookers leave all the available versions in windows so people from all parts of the globe can use their rom and see the bands for their country.

850 mhz Radio ?
did found this information quite old but HOPE.
"Sure, devoted ROM cooks were able to give the Euro-spec HTC Touch Diamond some 850Mhz frequency capability. And then HTC came out with their own ROM update that gave the HTC Touch Diamond EDGE-support on the 850Mhz band. But, without a dedicated 850/1900Mhz 3G radio under the hood, the HTC Touch Diamond just couldn’t crack the US market like we’d hoped."
SO is there a Radio, because the 850mhz is there and to get 3G seems a Radio Issue

HTC DESIRE 8181 V's 8183 NEXT G DESIRE:

i found this on another forum. thought it be good for the confused ones thinking of buying. hope this explains a little better
So your looking to pick up a HTC Desire of eBay reasonably soon.
Is there any difference between Aus (delivered/imported 8181 Desires on eBay) vs NextG 8183 branded HTC Desires sold on eBay ?
because The NextG 8183 ones on eBay are currently fetching approx $100 more than none NextG 8181 Branded ones.
Q:
Is there any difference between Aus delivered/imported Desires (on eBay) vs NextG branded HTC Desires sold on eBay. From what I can tell they should all support the same frequency space, so there shouldnt be any difference.
A:
There are two different models of Desire....
Telstra sells one that supports UMTS 850/2100 The actual Telstra Next G branded ones have got some Telstra "Apps" loaded into the ROM which cannot be easily removed, however they are simply links to Telstra services. They are unlocked.
Models sourced overseas usually support UMTS 900/2100, which won't work on NextG.
Pick wisely.
Q:
The NextG Versions will still operate on Optus/Voda/etc right? The frequency ranges all seems to match up. Some online stores are selling NextG and none NextG versions, just dont want to shoot myself in the foot.
A:
Yes, the Next G version will work on Optus 3G, but only in metro areas. It does not support the 900 MHz frequency used by Optus or Voda in regional areas, meaning outside city, you'll only get 2G.
It does not support the 900 MHz frequency used by Optus or Voda in regional areas
Hmmm ok, thats weird because according to the HTC Site (and this is where im getting confused) with all the "Exclusive to Telstra NextG" Branding, it supports the following
HSPA/WCDMA:
* Australia: 850/2100 MHz
GSM:
* Australia: 850/900/1800/1900 MHz
Q:
Do they cripple the NextG version and rip out the 900mhz ?
A:
Australia: 850/900/1800/1900 MHz
Those are GSM frequencies, not UMTS.
To make it abundantly clear:
Telstra specs:
HSPA/WCDMA:
•Australia: 850/2100 MHz
GSM:
•Australia: 850/900/1800/1900 MHz
Optus specs:
HSPA/WCDMA:
•Australia: 900/2100 MHz
GSM:
•Australia: 850/900/1800/1900 MHz
3G is around the world but Yes the US carrier At&T use it..
To help you, AT&T use the 850MHZ band while the other mobiles providers (ie T-Mobile) all use the 900 etc if you are grey importing a US phone the rule of thumb is if the phone works on AT&T then it will work on Telstra 3G network..
Telstra have two different 3G networks and they are 'branded' differently, yet they are both technically 3G at the end of the day.
1. Telstra 3G = 2100mhz, is only implemented in metropolian areas.
2. Telstra NextG = 850mhz, is implemented Australia wide and superceeds their 2100mhz implementation.
As you can see they are both 3G. The NextG branded product has more bandwith available to it, (not that 2100 doesn't have enough, just the way Telstra's implementation is).
Speed wise, telstra do have the fastest network, but in time, others will catch up. NextG is not some magical creative, even if Telstra subtly make you think that.
The issue with handsets is that they either come in 850/2100 variants (i.e compable on Telstra 850 3G) or 900/2100 variants (compatible with other networks in australia including the Telstra 3g branded service on the 2100 network).
Futher, this is not to be confused with similar GSM frequencies (then you get 2G coverage)
Q:
So is NextG just better coverage, or is it faster too? I was lead to believe there was a speed increase.
A:
Both.
The downside to having more coverage and web speed, is being stuck with Telstra..
If you have voda or Optus, you need the desire A8181.. if you're with Telstra you need the A8183
I have Optus meaning my phone model is A8181 & it's $100+ cheaper
CHEERS:

This is well written explanation, I'm sure it/has helped many ;-)

Rural coverage for HTC Desire with 3 Mobile
I just want to clarify if the same is applicable with 3 Mobile as Voda have meraged. I'm a 3 customer and I'm moving to Trentham, Victoria. 3 and Voda have said there would be call and text coverage only in the area. 3 is bringing out the Desire later this month but I don't know which one. I've been told there's more Telstra towers in the area but will not swap suppliers as I have a good plan from when they were Orange. Thanx for the help.

If you get an 81 and use telstra, it will be slower.
if you get an 83 and use a Non-telstra network, it will be slower.
If you get an 83 on telstra, Root and grab T-Mod.
Simple! XD

Hi there.
I am confused. I am thinking of getting A8183 and am a vodafone user. Will 3g work for me?

I'm pretty sure it says above only in metro areas mate

vodafone going 850mHz

I have the 8183, rooted and running on LiveConnected (Optus). I have very little drama with mobile internet, regardless where I use my phone around Cairns.
I find I get drop outs if I venture too far west, but north to Pt Douglas/Mossman, inland to Atherton Tablelands/Millaa Millaa/Malanda and all the way south to Townsville (including Hinchinbrook region), signal is strong and on song.
I have never understood people that gripe about their 8183s not working properly on other networks...unless they happen to live in Oodnadatta, there should not be an issue.

[Q] GSM or CDMA Desire?

Hi all, Firstly iv got a O2 UK branded desire. Iv already rooted it and im now running leedriod2.2 but my problem is I wish to also install the psfMod But im confused at which file I need to download, as the titlle suggests I need to know if its GSM or CDMA or how can I find this out. Thanks in advance.

Im almost certain this is wrong.
Its to do with the type of network you operator uses.
Can be found on the HBOOT Screen.
Bravo = GSM
Bravoc = CDMA

Well yes, it's down to the cellular network used, codecs used to transmit the data, different frequency and network structure. But in the most absolute laymans terms, GSM has a removable SIM card and CDMA doesn't.
He wanted to know what file to download for his Desire, not a comparative on the different standards adoped by each technology. So I gave him the most basic answer so he could go ahead and install the program to his phone, makes sense don't you think?

4G in
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
here is a little about it
In cellular service there are two main competing network technologies: Global System for Mobile Communications (GSM) and Code Division Multiple Access (CDMA). Cellular carriers including Sprint PCS, Cingular Wireless, Verizon and T-Mobile use one or the other. Understanding the difference between GSM and CDMA will allow you to choose a carrier that uses the preferable network technology for your needs.
The GSM Association is an international organization founded in 1987, dedicated to providing, developing, and overseeing the worldwide wireless standard of GSM. CDMA, a proprietary standard designed by Qualcomm in the United States, has been the dominant network standard for North America and parts of Asia. However, GSM networks continue to make inroads in the United States, as CDMA networks make progress in other parts of the world. There are camps on both sides that firmly believe either GSM or CDMA architecture is superior to the other. That said, to the non-invested consumer who simply wants bottom line information to make a choice, the following considerations may be helpful.
Coverage: The most important factor is getting service in the areas you will be using your phone. Upon viewing competitors' coverage maps you may discover that only GSM or CDMA carriers offer cellular service in your area. If so, there is no decision to be made, but most people will find that they do have a choice.
Data Transfer Speed: With the advent of cellular phones doing double and triple duty as streaming video devices, podcast receivers and email devices, speed is important to those who use the phone for more than making calls. CDMA has been traditionally faster than GSM, though both technologies continue to rapidly leapfrog along this path. Both boast "3G" standards, or 3rd generation technologies
also known as CDMA2000, is CDMA's answer to the need for speed with a downstream rate of about 2 megabits per second, though some reports suggest real world speeds are closer to 300-700 kilobits per second (kbps). This is comparable to basic DSL. As of fall 2005, EVDO is in the process of being deployed. It is not available everywhere and requires a phone that is CDMA2000 ready.
GSM's answer is EDGE (Enhanced Data Rates for GSM Evolution), which boasts data rates of up to 384 kbps with real world speeds reported closer to 70-140 kbps. With added technologies still in the works that include UMTS (Universal Mobile Telephone Standard) and HSDPA (High Speed Downlink Packet Access), speeds reportedly increase to about 275—380 kbps. This technology is also known as W-CDMA, but is incompatible with CDMA networks. An EDGE-ready phone is required.
In the case of EVDO, theoretical high traffic can degrade speed and performance, while the EDGE network is more susceptible to interference. Both require being within close range of a cell to get the best speeds, while performance decreases with distance.
Subscriber Identity Module (SIM) cards: In the United States only GSM phones use SIM cards. The removable SIM card allows phones to be instantly activated, interchanged, swapped out and upgraded, all without carrier intervention. The SIM itself is tied to the network, rather than the actual phone. Phones that are card-enabled can be used with any GSM carri
The CDMA equivalent, a R-UIM card, is only available in parts of Asia but remains on the horizon for the U.S. market. CDMA carriers in the U.S. require proprietary handsets that are linked to one carrier only and are not card-enabled. To upgrade a CDMA phone, the carrier must deactivate the old phone then activate the new one. The old phone becomes useless.
Roaming: For the most part, both networks have fairly concentrated coverage in major cities and along major highways. GSM carriers, however, have roaming contracts with other GSM carriers, allowing wider coverage of more rural areas, generally speaking, often without roaming charges to the customer. CDMA networks may not cover rural areas as well as GSM carriers, and though they may contract with GSM cells for roaming in more rural areas, the charge to the customer will generally be significantly higher.
International Roaming: If you need to make calls to other countries, a GSM carrier can offer international roaming, as GSM networks dominate the world market. If you travel to other countries you can even use your GSM cell phone abroad, providing it is a quad-band phone (850/900/1800/1900 MHz). By purchasing a SIM card with minutes and a local number in the country you are visiting, you can make calls against the card to save yourself international roaming charges from your carrier back home. CDMA phones that are not card-enabled do not have this capability, however there are several countries that use CDMA networks. Check with your CDMA provider for your specific requirements.
According CDG.org, CDMA networks support over 270 million subscribers worldwide, while GSM.org tallies up their score at over 1 billion. As CDMA phones become R-UIM enabled and roaming contracts between networks improve, integration of the standards might eventually make differences all but transparent to the consumer.
The chief GSM carriers in the United States are Cingular Wireless, recently merged with AT&T Wireless, and T-Mobile USA. Major CDMA carriers are Sprint PCS, Verizon and Virgin Mobile. There are also several smaller cellular companies on both networks.

In most cases I've seen, GSM are European variants of the device and CDMA are usually US devices.
That is just from my own experience though, so I could be wrong..

[Q] Change Defy 3G Frequency?

Hello I live in New Zealand and we have a network here called Telecom XT which uses 3G freq: 850 & 2100 mhz.
Unfortunately all Motorola Defy sold here have their freq specified as: 3G Network: HSDPA 900 / 2100
I see in the development section there is a way to flash files to restore 3G coverage and one of the files has the 850 & 2100mhz that our Telecom XT network uses. Does this mean I can flash this file to enable those frequencies on this phone or does it mean that the Chinese versions of Defy have a different chip that supports the different frequency?

Hey,
Unless the Defy has a tri band WCDMA chip (which im pretty sure it doesn't) then you can't simply flash new radio firmware/RIL to enable frequencies.
If you want an XT compatible desire, your best bet is something from T-Mobile or more ideally Telstra Australia's NextG network, which is the same as XT. Mobicity for example sells NextG handsets which will work perfectly on XT.
If you have the 900mhz Defy i believe you are limited to Vodafone/2Degrees. Flashing these Radio/RIL fixes i think were because those with 850mhz handsets with issues running radios designed for 900mhz.

Just to confirm, Defy hardware can only do certain pairs of frequencies (e.g. as say mentioned on gsmarena.com) irrespective of what ROM is put on it ?
Is there anyway to find out (from model/serial number or other way) what hardware one has ? (for 3G frequency)
I'm pretty sure about mine, though I bought this Defy 2nd-hand and flashed it, so just wanted to be sure. (I flashed it with 900/2100 MHz ROM and it seems to work fine on T-Mobile 3G in London, UK. But wonder if there is a way to check - perhaps for another unit....)
