i have a Euro Diamond in the US and as we all know tmobile 3G is 1700/2100MHz i have:
UMTS(2100)+GSM(900+1800)
UMTS(850+1900)+GSM(850+1900)
UMTS(800+2100)
UMTS(850+2100)+GSM(900+1800)
UMTS(850)+GSM(900+1800)
UMTS(1700)
so i was wondering if there was anyway to combined 1700+2100 so I could use 3G for T-Mobile

Tmobile 3G is going to released on UMTS 1700 Mhz and UMTS 2100 Mhz Bandwidth.. and GSM works on 1900Mhz and 850Mhz for roaming.
But I see none of the bandwidth selections in 1.0.25.05 Radio have those 4 together. is it possible to get those 4 bandwidths into one grouping on the NEXT Radio UPDATE??
JUST A GENERAL QUESTION!! PLEASE DO LET ME KNOW
HTC TOUCH DIAMOND
BElite 0.95 ROM
Radio 1.00.25.05
TF3D : 1.1.34569.0_1630.38
I bought my Diamond in HK-Asia where the 3G HSDPA is 2100Mhz. But I would like use it in Brazil where the 3G HSDPA is 850Mhz. Could I load any USA Radio (where 3G is 850Mhz) on my device to convert from 2100Mhz to 850Mhz HSDPA? Will it works?
As i think with the Radio roms as they are Quad band it should work, if its not an CDMA diam
Edit: Okay, sorry just speculation !
no you will not get 3g speed, only edge.
Finally decided to get a T-Mobile US TP2
Q0. Other than the looks, what else is different between the International Unbranded HTC TP2 and the US T-Mobile TP2
Q1. I've been told the US 3G bands are different from the Asian / UK 3G bands. The Asian bands if I'm not mistaken are "HSDPA 900 / 2100". Can anybody cite the US bands? Also I know that 2100 is common for both US and UK... will that be enough to use 3G in Asia?
Q2. Obviously I would need to get the phone SIM unlocked. For once I couldn't find anthing on XDA to unlock the TP2. Any light on that would be great
Q3. I noticed that Hard-SPL is now available for TP2. I'm assuming that means I can flash it with any ROM. Would doing that automatically unlock the phone to be used with any SIM?
Need answers to these real fast guys... got a good deal on eBay.
0. mostly looks and 3g bands
1. tmobile 3g is strictly for tmobile 3g. anywhere else and its edge for you
2. no free sim-unlocker yet
3. Hardspl is for flashing roms...completely separate from sim cards
Oh man... that sux. I was really hoping that atleast one of the T-mobile bands would be compatible with the Asian 3G bands. Do you have any idea what bands T-Mobile operates on?
HSPA/WCDMA
1700/2100 MHz
Note the 2100 band is part of AWS which means it's not compatible with Asia 2100. T-Mobile 3G requires both 1700 and 2100 to operate. One band is upload and one is download.
Quad-band GSM/GPRS/EDGE
Quad-band 850/900/1800/1900 MHz
What exactly is the AWS?

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?
idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry
I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix
It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.
This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.
T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.
Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different
OK call me foolish but I got fed up with TMobile and switched to ATT because the company offered to pay my data plan to keep me on call. I had been saying no but a billing problem that they refused to fix left me steamed. Anyway, is there anyway to make AT&T 3G work on my Tmobile TP2?
T-mobile is only edge...you cant use 3g unless you have a tilt 2

Let me rephrase that, for all the people that got "confusimacated" at first glance (like me)
The T-Mobile TP2 will work on AT&T's system, but it will only be capable of EDGE, and not 3G due to the fact that AT&T's and T-Mobile's 3G service use different frequencies.
Overseas Version
I have the overseas HD2 (LEO) which in not branded by T-Mobile. I also have ATT, can i get 3g on it?
at&t 3G is on the WCDMA 850/1900 megahertz bands. The Leo operates on EU frequencies, 900/2100 WCDMA for 3G service. Your Tmobile gets 3G on the 1700 MGHZ band. You need a phone with NA 3G frequencies to get 3G from at&t, and those are 850/1900 WCDMA. None of your devices will see 3G here in NA. Europe operates 3G on 1900 and 2100 and a few on 900 WCDMA, Japan and South Korea are on 2100 WCDMA only and NA is on 850/1900, so you need to be really careful of the hardware you purchase for it to work where you want it to and at the speeds you want. Edge comes on the older GSM frequencies and almost all phones have the 4 GSM frequencies, 850-900-1900-1800, but none have all the GSM and all the WCDMA frequencies, could but don't. Most US phones will have 3 WCDMA frequencies, 850-1900-2100. Better to buy an unlocked tilt 2 or sign an agreeement with at&t for a discounted phone.
Good luck.
