CEX.co.uk are offering £157 for an unlocked iphone. Id say if it was jailbroken they would refuse to buy it. My iphone was not working well ,it would not turn on so I had to restore it. Now I can go ahead and use pwnage to unlock and jailbreak it. I dont want to do this, is there no program for the mac or windows that will simply activate and unlock my iphone 2g. I presume its the latest 3 firmware as it was just restored today.
You're going to need to jailbreak it with an app. No, nothing just "unlocks" it without a jailbreak. If you want a guide, check out the wiki section of the link in my sig.
