This is weird, i already make a backup of my iphone before restoring.. I also double check on Mobilesync folder to make sure its there.. EVen in itunes preferences-->device tab, there's my device name, so im sure i did my backup correctly.. After restoring, there's an option weather set up new phone or restore from backup , i was in a hurry and i choose "set up new phone" cos i taught i will do the restoring later.. But when i wanna restore frm backup, i cant see my previosly device name?! im sure its not deleted cos my drive space is still the same.. I hope someone could help me..
