Most of Miami already has 4g and pines is supposed to be. Within the next 2 weeks or so.
I'm have no problem with ATT and love my iphone 3G. But time has come and I'm allow to upgrade to Iphone 4. I'm going to pre-order mine on June 15th.
We'll see how long the Iphone wanna bees take to come up with their version of FACETIME...
