OK, so I'm currently using an iPhone 2G unlocked, with the APN data block, and also a data block on the AT&T side, been using on AT&T no problems, no data for over a year. Now I want to upgrade to the 3G, I have a 3G sitting here unactivated, can I jailbreak/unlock/hacktivate (when the new unlock comes out of course) and then do the APN blocker for good measure and be all set? Thanks
