Seems like xperia ion is rocking the market. In my area, i found more than 20 guys bought this since its launch. Now as i was also in search of a new mobile, am think to go with the same. But when i compared xperia ion price with various vendors i found that At&T is offering the cheapest. But as am using T-Mobile since years, i want to continue with the same and dont want to have Xperia ion with AT&T. So am here to ask if it is possible to unlock AT&T off-contract in any way ?
