Sorry if this has been asked before, I searched and couldn't find anything. I have a new iPhone 3GS, and it's at 3.1.3. I want to jailbreak it, but I obviously haven't succeeded. I was wondering if there is a master reset within the phone, "Erase All Content and Settings", or maybe software that could do it, besides iTunes? There's got to be a way to reset the firmware to the stock one that it came with, without having to go through so much hassle. If there is, I'd be glad to know, I'm sure so would others.
