Trade: white sony ericsson x10i for sony ericsson x10a (prefer white, but ill take black) was using it here for t-mobile usa but Im on a family plan and my buddies wanted to go at&t. It's mint condition and only 2wks old. Works really fast on t-mo 3g. I just need the x10a for it's at&t 3g bands. Let me know if there's anything else you guys want to know about the phone. It's unlocked and unbranded.
