Unlock iOS 4.0.2 iPhone 3GS with UltraSn0w 1.1-1

A couple of days back, we discovered that the only iPhone that can be jailbroken on iOS 4.0.2 is iPhone 3G. Anyone having iOS 4.0.2 on their devices was simply out of luck to jailbreak iPhone 4 and iPhone 3GS.

But looks like there is already a workaround for that. You can jailbreak iOS 4.0.2 and then unlock iPhone 3GS (on 4.0.2 iOS) with Ultrasn0w 1.1-1.

All you have to do is jailbreak iPhone 3GS with a custom firmware with an old bootrom using PwnageTool. Once you jailbreak it, you can unlock iPhone 3GS with iOS 4.0.2 because the iOS 4.0.2 and 4.0.1 have the same baseband. The screenshot above says everything!
