Okay. I would like to Jailbreak my iPhone. I know how to jailbreak my iphone, with ZiPhone or iNdependence etc... I'm just really scared I won't be able to take it back to un-jailbroken before the new firmware comes out. I know it will probably void my warranty, but is there a way to take it back so noone would ever know it was jailbroken? Basically, I want to know the risks, and if its possible to completely erase all traces of being jailbroken. Thanks.
