iOS 4.3 could not activate cellular…: Apple Support Communities. I had a friend who had this problem today on her iPhone 3GS. I did the standard troubleshooting things the first person on this thread did. It didn’t seem to solve the problem. I turned the phone off for a minute and then turned it back on. That seemed to solve the issue.
Interesting. I was preparing to call AT&T and see if this was a carrier issue. This happened after using an iHome speaker for the first time today. Has anyone else noticed this?
To look in the ~/Library/iTunes/Mobile Backups folder to find the Manifest.plist folder, and delete entries for apps that might be causing the problem.
I remembered that a little while ago, I had started getting an error message while syncing and updated app (Sleepmaker or something- couldn’t remember which, precisely, but knew that it was a white noise app). So, I went to the Manifest.plist folder, and removed the entries for the couple different flavors of the Sleepmaker app that I had installed.
Then, reconnected the iPhone, and clicked “Continue Restore” once again when it reported that there had been an interrupted restore. This time, it went through fully! Took quite a while (~1 hr) to copy all my media onto the phone, but now it’s all there! Hopefully this will help others who might in the same situation…
