The last couple of days when I launch iTunes, I get a dialog box saying "This copy of iTunes will expire in __ hours." I'm running 8.2b7 (beta version); and wanted to stick with this one in case anything happened to my iPhone 3G and I need to rejailbreak it and upload the correct AT&T file for MMS and tethering to work. From what I understand the later versions of iTunes won't let me choose which carrier file to send to the iPhone. Anyone who has upgraded beyond 8.2, can you option-click (on a Mac) and choose which carrier file to send to the phone? Thanks in advance for your help!
