The iPhone 3.1 software update, which was issued yesterday, has caused some handsets to freeze and get stuck in a restore "loop". It means the device is wiped of all content, and cannot be used to make or receive calls. Downgrading to the previous 3.0 operating system is also proving difficult for users. "I've been trying everything I've found on trouble shooting pages and on some searches," writes a user, Batwing, on Apple's support forums. "I'm getting numerical errors after the phone/computer tries to restore to 3.1. (6, 14, etc.) I've reinstalled iTunes, tried restoring on 3 different computers, held down power/home buttons, moving to different USB slots..."
"I've been able to restore back to 3.0, but trying to update to 3.1 gets the iPhone stuck in recovery mode every time," writes ThisIsTheChris. "I tried to upgrade to 3.1 also and now am the proud owner of an expensive doorstop," writes John Gordon Doty. "Does Apple ever test these upgrades? They must, but it sure makes you wonder when so many people have the same problem with the same software."
Disgruntled iPhone owners have also been using Twitter to discuss the issue and find solutions. "Still waiting on restore on my iPhone. 45 minutes and counting. Beware the 3.1 update – make sure you're backed up," warned Grvychk. It is not known how many iPhone users are affected by the software problems, nor what has caused dozens of devices to crash. Apple has not commented on the situation, although it is likely that engineers are already working on resolving the problem. The new iPhone software was unveiled by Apple's chief executive Steve Jobs, who underwent a liver transplant earlier this year and last made a public appearance in October 2008. He also showcased a new iPod nano with built-in video camera, spec bumps to the iPod touch and iPod Classic range, and a new version of iTunes with features such as iTunes LP, which downloads sleevenotes and artist videos whenever a user buys an album, and Genius Mixes, which auto-generates playlists of "songs that go great together".( www.telegraph.co.uk)
