Here’s some quick advice for all of you folks who want to upgrade to the iPhone 2.0 software, especially if you need a usable iPhone in the next few hours: WAIT!
Apple’s servers are clearly slammed (Me.com is virtually inaccessible) and after installing the 2.0 software and firmware, my phone couldn’t access the iTunes Store and has been rendered inoperable. Good thing I don’t need it right this minute and can retry in an hour or so.
A few others are having the same problem.
