I am an Android guy, thinking of possibly changing to either the Verizon or ATT iPhone4, for better battery life, and other reasons, just want to try something new and different. But would only do so, if I know for sure the phone can be jailbroke right of the box ? Untethered of course. I have never owned a iPhone, don't know anything about jailbreaking, but I root and install custom ROM's on my Android phones all the time, so I am sure I can figure it. So if I walk out of the phone store, with a brand new iPhone4, can it be done, or do they come out of the box with the latest update pre installed, and no jailbreak for the newest OS update ?
