ok so i bought a 4GB iphone (ya i know ) ok so it has apple care until 2009 it was always used on att and never jailbroken or unlocked... should i take a trip to buffallo (as i live in toronto canada) before i jailbreak it and get it replaced??

anyone... please i really need to know asap before i rush into using it

Is there a problem with the phone that u need to take it back to apple??
If there is no problem just jailbrak the phone and then u can use it

no there isnt a problem other than its 4gb and since apple sold all the 4gb maybe they will give me an 8gb... but my main question is does virginizing the phone make it undetectable?
