Just got round to updating my wife's iPhone 3G to iOS4. The backup portion took overnight then gave an error message to say it was unsuccessful (although it has been successful all previous times before or since.) When the update was complete, the phone was totally blank, photos, e-mails, MMS, music, vids, apps all gone. Sync'ing through iTunes has restored the music, videos and apps however the text messages, e-mail history and photos are still gone (although I do have all the photos on iPhoto.) Anybody know how to get these back? The e-mail history is quite significant for her business and the text messages for sentimental reasons. These should be contained in the previous backups but where are they held, how do I access them? Thanks for any advice.
