Ok so I had a jailbroken iPhone as of this morning but I'm having problems with it so I decided to restore it and upgrade to 3.1.3 but in iTunes when I restore it and had NOTHING in it it says I have 188mb used is this from my previous apps that were in there that didn't get completly taken off or is this normal? Because I got a appoitment with apple this Monday to take in my phone and get it swapped for a new one can any1 tell me if it's safe to take to apple like this?
