I have an AT&T contract and recently updated my phone to 1.1.1. I don't like it and want to go back to 1.0.2. I've read several articles about how to do it, but it is confusing as to whether a legit, locked AT&T phone will function as a phone after a downgrade. I have downloaded the 1.0.2 restore, INdependence, and AppTapp installer. I'm really confused by the statements that talk about re-unlocking or the phone function not working. Any help would be greatly appreciated!
