T-Mobile US runs on 1700Mhz, not 2100Mhz. So even the European 3G phones will not work for T-Mobile here in the US.
Here is the 3G band deployments across the world:
UMTS/HSDPA/HSUPA frequency bands deployment
* Band I (W-CDMA 2100) in Europe, Africa, Asia, Oceania (ITU Region 1) and Brazil (part of ITU Region 2)
* Band II (W-CDMA 1900) in North America and South America (ITU Region 2)
* Band IV (W-CDMA 1700 or Advanced Wireless Services) in the United States (T-Mobile USA)
* Band V (W-CDMA 850) in America, Canada, parts of South America, parts of Asia (ITU Region 2 and ITU Region 3)
* Band VIII (W-CDMA 900) in Europe, Asia, Oceania (ITU Region 1 and ITU Region 3)

Second of all, even if you get an unlocked phone you can forget about 3G for a long time: - AT&T runs 3G at 850Mhz and 1900Mhz. T-Mobile USA runs 3G at 2100Mhz. Unless Apple supports 2100Mhz as well, 3G will never work on the iPhone under T-Mobile. However, Europe uses 2100Mhz, so you might be able to get a hold on a European iPhone and unlock it. Big hassle tho if you ask me.
- T-Mobile only offers 3G in New York currently. They have plans to release it nationwide, but it will literally take years. You'll have to check their release schedule for your specific state.
I'm on T-Mobile USA, and I'm thinking I'm gonna have to switch back to AT&T. Not too worried but it just means another break the contract $200 fee, which always sucks.
Correct me if I'm wrong on any of this... |
