4.0 software is beyond terrible so I wanted to go back to 3.1.3. 3G on at&t btw.. followed these instructions to the letter....backed up just as it says in the first steps... http://iphonetouch.blorge.com/2010/06/28/how-to-re-install-iphone-os-3-1-3/ when bringing it back up, I got the version is too old for the restore error, so I had to restore as new iphone.... I have apps and music but contacts, bookmarks and photos are gone. I tried to choose a different 'back-up from restore' but the only back-ups shown are after the data loss. anyway to recover?? I'm in need of help...thanks!!
