Hi Xperia enthusiasts! Currently I am located in the USA using T-mobile as my provider with an Xperia X10 Mini Pro and I love it. I still plan on using it when I get my Ion due to its compact nature, however the reason i want to upgrade is that I am paying for 4G and my X10 only does 3G. If I unlock the AT&T Ion or just get the LT28i will it be 4G compatible or is it only for AT&T networks??
I don't know at&t networks, but in France same network have HSPAP !!! It's an lte/4G with a low ping and more bandwith !
