Upgraded iphone 4 to 4.1 software this afternoon. Iphone synced and all seemed well until when trying to send a message the iphone crashed and returned to home screen. When loading up messages again all the messages gone. Connected up to computer and the iphone synced automatically which has deleted all the messages from the backup too. SO when i did a restore there are still no messages!!! Not the end of the world - bit frustrating but does anyone know why this happened?? Can i get the sms messages back? Have looked through the backup folder and can't find backup from earlier than the one which happened as soon as i connected the iphone after the bloomin messages were deleted!!
