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?

try under the MORE tab in phone settings, frequency in BAND SELECTION should be set to automatic.

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 ;\

Frequency Change?

Hello,
It has been a long time since I even dared to visit this forum. Last time I asked a question here I was met with so much ignorance and stupidity I swore I would never come back or recommend this site. But Xda has a lot of excellent info, and I refuse to believe all members are nasty. Hopefully I get a much kinder response!!!
My question is: can a phones 3G frequency be changed internally or via software? I plan to buy a Rhodium which has European 3G freq (2100Mhz). I wanted to get it thru T-Mobile but they are going to change the color and shape of the phone and I would rather get the original from either "On the go solutions" or I am open for suggestions. Is it possible to change it's freq so it will be US 3G for T-Mobile?? Please be gentle with me. I am not sure what I can ask here, without being chewed up!!

I have the same question. Does anyone know the answer?

The answer to your question is no. 3G radios are hardware dependent, not software. The only Rhodium that can access T-Mobile's 3G network is the T-Mobile branded one (Rhod210). There is no other Touch Pro2 that operates on the AWS band that they use. EDGE and GPRS will work fine, however.
T-Mobile US operates on the AWS 1700/2100 MHz frequency band. European 3G operates on the IMT 2100 MHz frequency. I know what you're thinking: "You just said T-Mobile uses the 2100 MHz frequency; why won't the European TP2 work?" The answer is not that complicated. 3G operates on two different frequencies. There is one for uploads and one for downloads. T-Mobile's US market uses the 1710 - 1755 MHz spectrum for uploads and the 2110 - 2155 MHz spectrum for downloads. The European market is said to use the the 2100 MHz band, but this is only partly true. It uses two different frequency ranges and just markets it under one band number. It's uploads are in the 1920 - 1980 MHz range, while downloads are in the 2110 - 2170 MHz range.
Hopefully this explains everything for you. I liked the look of the European one too, before I got mine. It's grown on me. I wouldn't trade it for anything. I would like to have a PTT button, and a front facing camera, but video calls don't work in the US on this device anyway, and I have no real need for a PTT button. On the other hand, T-Mobile owners have a big advantage when it comes to flashing. Our reset button is on the outside of the device. Other devices have to remove the battery cover to get to it.

How does 3 G Work ???

Supposing 2.1 GHz (2100 MHz) is allocated for 3G, how will 3G work..
Will it require another frequency slot such as 900 MHz to upload and use the existing 2100 MHz to Download data ???
or use the same 2100 MHz for all types of tranfers viz., both Upload and Download ???
Please Clarify...
Note : My understanding is that it shall use the same frequency band to UPLOAD / DOWNLOAD Data as well....

Before your fingers get shot, type the subject on google and check the first link... that way you won't get the, use the search button excuse etc etc.

3G doesn't need a specific band like 2100MHz to work. Like most other wireless technologies, it can work with many different frequencies. However, carriers have certain bands licensed to them. Obviously they don't wan't to share the same frequencies because conflicts arise.
3rd Generation wireless technologies also don't need one wireless band for upstream, one for downstream... but separating the two makes each piece faster. Therefore carriers usually use HSDPA and HSUPA (3.5G wireless technologies) on different bands... like 900/2100.
But to answer the real butt of your question: no you can't get 3G on your device unless it is specifically designed to work for your 3G network provider. It doesn't matter if it supports only one of your carrier's frequencies, or even both of them (because there are sub-bands as well).
If you need a 3G device, buy it from your carrier or make sure that you know which exact carriers it is designed to work on.

I think you ask the wrong forum.
I will suggest you to google on the following:
WCDMA
HSDPA HSUPA
UMTS
This will give you a brief idea. If not, there are plenty of books and classes you can take...

Actually, each of the listed bands is typically listed into uplink and downlink allocations. I think for UMTS uplink is a bit below 2100, and downlink is above. It's been a while.
Either way, Google it.

Enabling HSPA: 850/1900 on the Global Version (GSM/CDMA)

Does any body know if it is possible and if so how to enable the HSPA: 850/1900 band on a Global (GSM/CDMA) Version of the TP2.
It already has the HSPA: 2100 enabled... so maybe someone RF inclined could shed some light on this question.
Thanks

I dont believe it has the hardware to do it. It is not a software tweak.
That is why so many people waited for the ATT version to come out. There is an Australian version that works on one of the bands but not both.

Sorry to say that I think you are wrong about the Hardware reason...
Apparently the Pro2 has the chip installed, but it's locked down some how. That info has been floating around from an inside source at Telus. they say it actually has 850/1900/2100 UTMS bands but just got "locked" by Telus.
Also sites like Engaget has long posted some HTC FCC info proving that; http://www.engadget.com/2009/05/20/htc-passes-cdma-gsm-hybrid-touch-pro2-through-the-fcc/
Also The TP2 uses Qualcomm's MSM7600. The specs for that processor allow two major sets of radio interfaces, only one of which supports CDMA 800 and 1900. That major set has two variants that support HSPA: 2100+800 or 2100+1900+850.
So the question is; is there anyone with the proper knowledge that can tell what is onboard the TELUS TP2 and if it has infact the variant that supports the North American frequencies, how do we enable it?
Thanks for posting with FACTS and not Thoughts as this is the only way we will get a valid answer to this question.

Hmm this is definitely an interesting idea. I'd love to have the front facing camera of the Global Version, but I still need 850/1900 UMTS

850/1900 WCDMA on Global version
Gentlemen:
While the chipset has the various frequency capabilities, it is the tuning of the antannae that determines which frequencies are recieveable , ie, turned on, in the various versions. The AT&T version has a different tuning of the antannae than the global versions.
While theoretically possible, the anatanne is part of the main board and must be physically removed and replaced. I have not been able to find a universal antannae that could be resoldered to the board, if one was brave enough to give it a try.
there is software changes to the chipset controller required as well.
I think it is pretty impractical and likely impossible to do outside of have a new board installed with the properly tuned antannae to make it work. I have researched this for some time now, in an attempt to be able to use the EU versions here in NA. I travel internationally a lot, to Asia and EU, and need the 2100 band, so that has been my motivation.
There may be someone else out there who has different information, but this is what I have learned in digging through the available data for the past 3-4 years of various HTC devices and their variants.
Hope this helps,
MWS

Regarding Custom ROMS

Hi there
Firstly.. No, this is not a typical noobie thread asking for the best custom ROM out there, as I know it's related to personal preference. My problem is that I have a download limit, so I can not test out every ROM I'd like to.
A solution to this problem would be if you guys could recommend a few of the fastest ROMs for me, in your experiences (I'm not so interested in eye candy, more usability.. and most importantly I want it AS SMOOOOOTH AS POSSIBLE, I love smoooothness ) After a few ROMs are recommended I'll have a better picture of what to check out and what to download and I won't be wasting toomuch of my download limit.
Thanks in advance

Why do you have a download limit? What is your limit?

I live in South Africa where not everyone has unlimited internet.. My download limit is 5gb a month (but thats for my whole family...) , but I'm pretty close to blowing it :-/

C'mon, can't anyone help me out here?

I think you should start a new thread (search first) entitled "Fastest Custom ROM?" That will get a discussion started, and people who are interested in the subject will see the title and post their opinions.

I'll try that.. I wanted to avoid that though, 'cause I didn't want this to be those typical "What is the best custom ROM?" threads, and recieve the typical reply of "There is no best custom ROM"

Just sort the forum by the ROM w/ the most posts or views. If you go with those they will most likely be the most tested, have more user support/solution, and they have gone through a couple different versions.

Yes, but the specific question is which is the FASTEST ROM.

I tried a couple roms and decided I hated 6.5, so I cannot say for sure...but I can point you in a direction to check threads...
Energy, Cell, Josh, and DeepShining have all had very positive responses, and speed is something commonly mentioned among the pluses.
I hope this helps. Perhaps reading those particular threads can help you decide before wasting bandwidth.

In other words it is literally impossible to tell. The fastest ROM will be a today screen or titanium with no mods, it really boils down to what you want your phone to do though. I personally like eye candy and stability, you can see what I've chosen below for those. Don't get me wrong, it is still pretty fast, just not as fast as a bone stock ROM would be. I'd be willing to download, burn, and send a DVD full of ROMs, let me know.

WOW! That DVD would be TRULY awesome, and I'd REALLY REALLY appreciate it. How can we go about doing this kind sir?

I have tested out LOADS of ROMs.
But I always go back to one in particular,
Touch X "SENSE 2.0B X-TREME"
Now unfortunately this ROM has been dis-continued.
But 2.0 is still available for download:

For speed its great. If I have no today plugin running when i soft reset, there's only 36% memory usage.
Manilla reaps the memory a bit, having around 50% memory usage after soft reset.
Which is why I use other today plugins like 'iphone today' and 'throttlelauncher'
Over all its the the best (in my personal opinion mind)
And its not littered with unnecessary apps
