While iPhone 4 owners currently sit and wait patiently for their unlock method, we have some good news for those of you with an iPhone 3GS who have updated to the iOS 4.2 beta for developers.
If you would like to try this out, you can jailbreak your handset using the old bootrom along with PwnageTool, and then unlock it afterwards using UltraSn0w. As usual, RedmondPie has compiled the easy to follow guidelines up on their website, along with some useful screenshots in case you get stuck at a particular stage.
Let us know how you get on.
