I am sellig my 8gb iPhone on eBay and I want to have it unlocked. I used ZiPhone last night but there are problems with the iPod and YouTube and I would rather not install tons of fixers with the chance of bricking it. What is the best method to unlock/jailbreak an iPhone for a sale? I know on ZiPhone it gave options like "Jailbreak" and "Jailbreak, Unlock, Activate." Do I have to activate it for it to work for people with other carriers or can I just unlock and jailbreak? Would they have to do something to activate it again- it has already been activated with AT&T. This may be a stupid question but I just want to make sure.
