I have a question. I have used my 3g iPhone jailbroken from the day the dev team jailbroke it for us all. Recently though I've noticed some oddities with my iPhone. Signal has been weak, it is freqently searching for a signal. And the other day I had a huge blue dot in the middle of my screen that wouldn't go away, even across reboots. It did finally disappear. But I suspect hardware issues, and i want to take it into apple. Obviously, I don't want to take it in jailbroken, but I hear that they can get data from the phone that shows dropped call info and other stats. If I do a restore and set it up as a new phone, without restoring my backup, is that data going to be wiped out? Will they be curious why I've got no usage stats?
