The iPhone Dev Team has posted PwnageTool 2.0.3.1, a revised version of the iPhone hacking utility released yesterday then quickly removed.

The earlier release had mis-set file-access permissions, preventing upgraded iPod Touch - the code works with the music player as well as Apple’s phone - from retaining Wi-Fi passwords and the like.

PwnageTool 2.0.3 was released this week to allow owners of these devices to upgrade to Apple’s latest firmware, iPhone 2.0.2. The utility opens - aka ‘jailbreaks’ - the Touch and all versions of the iPhone to third-party apps released outside Apple’s iTunes Application Store. It’ll also unlock the original iPhone, but not the iPhone 3G.
