I have an iPhone 4S on T-Mobile ($30 100 min 5GB data plan, i use Google Voice) and I'm currently looking for an Android smartphone to try out. I'm having trouble finding a relatively inexpensive (under $300, don't care if its used) phone that supports T-Mobiles Band IV 3G (1700/2100) AWS spectrum. I've looked at the HTC One S, the Motorola Atrix HD, and some Xperia phones. I just received an Xperia T in the mail but must return it as its the AT&T version which doesn't support AWS 3G. The One S looks nice but I'm worried about the lack of microSD and that it only has qHD resolution (I'd prefer 720p) The Atrix HD also looks nice but it lacks in the ROM department (specifically Cyanogenmod) So, any suggestions? Can anyone with the One S calm my fears about the resolution and no microSD? Any Atrix HD owners know of any reliable 4.2 ROMs that remove the AT&T bloat? Any other suggestions? It HAS to support both the 1900 MHz 3G AND the 1700/2100 (Band IV) 3G spectrum. MicroSD is very much preferred (unless I'm convinced otherwise) and 720p is preferred. Thanks.
