I synced / backed up my 3GS last night. Today, I plugged it in to restore it. I believe it synced again and backed itself up over my previous backup. I tried doing a system restore to this morning, but the backup is gone. Is there any way I can get my data back onto my iPhone 4? I downloaded Recuva to see what I could do, but the crazy way the backup files are named makes it hard to fix the issue.
