Oh, I know you must've not missed the new Pwn Tools 2.0 released by iPhone Dev Team not long ago. Although with the abundant applications ready at App Store, you still want more freedom in installing the apps you want, right? ;-)
But you may have missed important notes before downloading the 19.7MB-sized tools:
- It'll only "jailbreak" your iPhone 2.0, but not able to unlock it yet.
- The iPhone Dev Team only made it for Mac-based computers right now, so for Windows users must use this workaround guide found by iPhoneHacks. But with one thing you should keep in mind is that the workaround guide only works for the first gen iPhone, not the iPhone 3G.
