I am looking to Jailbreak & unlock my iphone 3g version 2.2.1 for tmobile. First question would be should I upgrade the software to a newer version ? If so I hear that it is harder (if not imposssible) to jailbreak the latest or the newer software versions. Whos software should I use and what is the link to the site to jailbreak. What do you think of Quickpwn ? I appreciate your help thank you Kevin
