Dev Team member MuscleNerd is teasing us again with a screenshot of PwnageTool jailbreak for iOS 4.1. Previously supposed to be released last Sunday, PwnageTool has obviously been postponed and we still don’t have any idea of when it will be available.

PwnageTool is a jailbreaking tool that allows you to update your iPhone to the latest jailbroken software while preserving the baseband so you can unlock your iPhone. This upcoming version of PwnageTool will work with the iPhone 3G, 3GS and iPhone 4. It will also work with the iPod Touch 2G, 3G, and 4G. Additionally, it will jailbreak the iPad and the new Apple TV

A few days ago, the Dev Team had released a video showing PwnageTool in action. At the time, it was believe that PwnageTool released would be imminent.
