Apple this morning released iTunes 7.7, which enables connectivity with the iPhone 3G and installation of iPhone OS 2.0 for first-generation iPhones and iPod touches.
The new release is available via software update or as a 48.3MB standalone download.
Freezes when iPod touch/iPhone is connected Users are experiencing some significant iPod touch/iPhone connectivity issues after the update, including system freezes when the devices are connected.

"So i installed iTunes 7.7 with via software update on my iMac running Mac OS X 10.5.4. Ever since I did, I can't plug my iPod or iPhone in without iTunes crashing and requiring a force quit. I have tried deleting the ipod and itunes plist files from both my user and system."
Bronson Elliot adds:
"I just upgraded to the new iTunes 7.7. The upgrade seemed to go just fine, however, when I open iTunes and try to plug in my 16GB iPod Touch, iTunes becomes unresponsive and I must force quit to get it back. The iPod Touch never shows up as a device within iTunes.
"I'm kind of stuck trying to figure out what to do next. I'm attempting to repair permissions now to see if maybe that will work. I'll keep you posted."
In some cases, this issue can be temporarily eliminated by deleting the following files:
Only way out of this is deleting the following plist files from ~/Library/Preferences/ (your user library preferences folder):
In addition, try unplugging your iPhone/iPod from your system before launching iTunes for the first time. Once iTunes is launched, plug the device in.
Music missing Some users have experienced an issue in which music is ostensibly missing from iTunes after the 7.7 update. This problem is most likely to occur if you have music stored outside the default location (~/Music).
In order to resolve the problem, go to iTunes preferences and then the Advanced tab, and then change the iTunes music folder location, and click to the location where you keep your music. The library should update.
No main window Other users are experiencing a more dire issue where no main window appears when iTunes 7.7 is launched. If this issue occurs, you may need to recreate the iTunes library as explained in this Knowledge Base article.
