iPhone 3GS 4.2.1 All my iPhone contacts was suddenly deleted today without any warning! Only thing I can think of, is that I updated to the latest version of the Springpad App in AppStore. Then later when I was going to call, all contacts gone! How can this happen?? I was lucky to sync all my contacts to my address book on my Macbook a while ago. I synced my contacts in iTunes again. But after this sync, all my contact pictures where mixed up! 2 major bugs in one day!
