Okay just finished testing Jail Break on iOS 4.0.1 and yeah it works pretty fine with following steps –
- ensure you have iOS 4.0 also available with you,
- upgrade your phone to iOS 4.0.1
- use redsn0w to jailbreak, but do not point to 4.0.1, rather point to iOS 4.0 and let redsn0w do the needful
- let you phone boot back to normal
- connect to a WiFi spot and use Cydia to download and install Ultrasn0w
- Damn that’s done, you are through upgrading your Phone to 4.0.1 and unlocked it to suite your requirements.
For caution, please follow the steps in my previous blog –
