I just jailbroke my 3G today to 3.0 firmware, and for the most part everything's okay, but I did loose quite a bit, as stupid me hasn't synced in like, a month. I'm kinda new to the whole back up thing, but I did copy the media folder, which should have everything I want back, right? one thing I lost was my second camera roll that I used with the swap camera roll app. when I tried placing all the pics I had from the backup folder I made, they did work, but the thumbnails were nonexistent. it seems 3.0 moved the place where the thumbs were stored? I dunno. is there a way to get it to generate new thumbs to get it back to the way it was? I'm also open to other ideas too if not. I can always upload them all and re download them, but that would probably get tedious. I'd like to avid it if I can. Next up, older sms. I tried replacing the new sms.db file with the old, but it didnt take, it just comes up blank when I check it on the phone, so I switched it back to the original 3.0 sms file.
