I currently have iOS 4.2.6 on my phone, so I assume this is greenpois0n jailbreak 4.2.6. In the time of the jailbreak, I've defintiely not exploited it to the extent that I thought I would, so I figured I'd go legal and set it to iOS5 and just pay for the apps legally. Granted, I only downloaded one app that costs $1, so no real loss. I tried following the standard directions of restoring the phone. Seems like backing up and syncing were successful, but got a message at the very end of downloading after waiting for an hour that my iphone could not be restored. The phone is still functional. Tried googling and searching for answers. Any help would be appreciated. Much thanks.
