iPhone Dev Team released version 2.0 of their tool to unlock and jailbreak iPhone and iPod Touch that I have already posted on this iPhone Hack tool post. The team just released the first update of its unlocking tool PwnageTool 2.0.1 since they release version 2.0.

Quoted from their release blog.

It auto-finds the bl39 and bl46 files better, if they’re on your computer

It creates the ~/Library/iTunes/Device Support/ folder if not present, which should help with some 1600 errors people have been having.

Many people have reported the PwnageTool not starting up at all (the icon never stops bouncing). This issue should be resolved now.

The Sparkle AppCast URL is fixed in this version

Always remember, if you don’t know what you are doing better not compromise everything and be sorry at the end.
