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, so automatic updates should work for future releases.
Because of the AppCast URL fix, we recommend that everyone who downloaded PwnageTool 2.0 get this version, if they want to stay up to date automatically.
If PwnageTool 2.0 pwned your phone correctly the first time, you do not need to pwn again with 2.0.1.
Now older IPhone users users can upgrade to firmware 2.0 and IPhone 3G users have a possibility to have jailbreaked IPhones. That is because PwnageTool 2.0 is released today. Download links are: mirror1, mirror2, mirror3.
Just a reminder: this tool jailbreaks and unlocks older iPhones, and jailbreaks iPhone 3Gs and iPod Touches. No unlock for Iphone 3G yet. The supported firmware is 2.0 only. Platform is Mac OS.
If you get Error 1600 from iTunes (or if you see in your log a failure to repare x12220000_4_Recovery.ipsw), try: mkdir “~/Library/iTunes/Device Support” ; if that directory already exists, remove any files in it. Then re-run PwnageTool.
Reminder: as of right now, there are no apps out for 2.0. Over the next few days some will come out. So do not update yet if you have some favorite 1.1.x apps you are using! 2.0 will not run 1.1.4 apps
