iOS 4 came out yesterday, and right after iTunes finished to install it on our iPhones we all wondered whether jailbreak was still possible. Yes, it is. Using an unofficial build of Pwangetool by Criminal90 floating around on the internet and a couple of tricks, I managed to jailbreak my iPhone 3GS and install Cydia on it. Check out the full tutorial after the break.
What you need:
- iTunes 9.2
- iPhone 3GS original iOS 4 firmware (download here)
- Custom Pwnagetool build by Criminal90 (download here)
- iPhone 3GS running iOS 4 GM or iPhone OS 3.1.2 (mine was running a jailbroken copy of iOS 4 GM) with old bootrom. 05.13.04 baseband.
