3g bands

You have to be careful about which device you're getting, for use on what network because 3G may not work. Sure, most people don't run into the problem but as it stands now, if you have a T-Mobile 3G capable device, it won't work on AT&T 3G and if you have an AT&T 3G device, it won't work with T-Mobile 3G. Motorola is looking to...

Maybe AT&T will acknowledge Android after all. According to the specs page of the Sony Ericsson XPERIA X10, the American version of the XPERIA X10 packs 3G bands that fit with AT&T and not T-Mobile. To quote:
