View Full Version : Warning before upgrading to ios4

5th July 2010, 09:44 AM
I upgraded my 2G iPod touch to ios4 a week ago. As a lot of others have experienced I am am getting terrible battery life so decided today to downgrade to 3.1.3 or 3.1.2.

It can't be done!

Apple have stopped signing OS versions prior to 4 for my device. So when I attempt the restore (option + Restore) and select the .ipsw file it will contact Apple's update server which will deny the request.

So I'm stuck, and angry (along with a lot of others in the same situation). :angry:

My advice is unless you're desperate for a new feature and are confident that ios4 performs well on your device stay then don't do it.
