Ok I'm a huge apple geek but honestly I just never payed attention t iPhone hacks and such. Never figured I would get one since they are rather expensive, but going to buy one this summer and now I need to know. Can you guys just explain to me what the different apps are.. jailbreak, ziphone..whatever they are.. i've heard the names tossed around but what do they do exactly... and should I...? obviously it voids the warranty but is their a way to hide or relock the phone before you take it to the apple store?
