Well, its almost impossible to mention the iphone and not mention “jailbreaking” Basically, your iPhone is your property and you can do with it as you see fit. This includes installing custom firmware that seems to mimic Apple’s features, while allowing unsanctioned apps to be installed. Now, I’ve been on the “Jailbreak” scene since firmware 1.1.2, and I have seen a number of different methods. The key to this process involves installing a alternative app known as “Cydia” Once this app in installed, a host of new features are available. The most notable for me was an app called Cycorder, which allowed users to record video, which was supposedly a feature unique to the 3GS. I’ve also noticed that many features somehow make it into apple official firmware. So, here is the best spot to get it done. The Iphonedlownload Blog. Happy Jailbreaking!

Ealier today, GeoHot unveiled BlackRa1n RC3, his latest jailbreak for iPhone OS 3.1.2. BlackRa1n RC3 is very similar to RC1 and RC2. The difference is that RC3 includes BlackSn0w, the unlock for iPhone baseband 05.11.07.
This step by steps guide and tutorial will show you how to jailbreak your iPhone OS 3.1.2 with BlackRa1n RC3. The steps are strictly identical to BlackRa1n RC1 and BlackRa1n RC2 but I figured it might be good to write a tutorial for novices.
This BlackRa1n RC3 iPhone jailbreak tutorial will work on both Mac and PC. If you already jailbroke your iPhone using BlackRa1n RC1 or RC2, there is no need for you to run BlackRa1n again.
