So I accidentally left my iPhone 3gS (jailbroken) on my dash and it got really hot. I came back to the car and it said I needed to restore the phone and it had no service. I try to restore from itunes and get error 23, try to re-jailbreak and no luck there. I've tried on a mac and on a PC to restore in DFU and restore modes. No dice. Now I'm desperate, I either need to get this one working or find a way to erase the data on the phone so apple can't tell I have it jailbroken. Let me know guys! Thanks!
