Anybody know of a way to activate a 3G w/ 3.0 w/out itunes and it properly work with AT&T? The reason I'm asking is I'm in the Navy and I will be able to download OS 3.0 tethered from my current 2.2.1 iPhone 3G but then I want to install the new OS right away bc I'm going right back out to sea for a few days and won't be able to activate through iTunes. Any suggestions? Thank you for your help.
