PwnageTool 4.1.3 Unlock Download Available
PwnageTool 4.1.3 has just been released and includes the ability to unlock iPhone 3G and 3GS with basebands later than 05.13.04 (iPhone 4 is apparently in the works). To do this, you will need to jailbreak using PwnageTool and then download Ultrasn0w for iOS 4.2.1 from Cydia. PwnageTool Unlock Edition works by using the iPad 3.2.2 IPSW file on basebands 05.14 and 05.15, this process is not reversible.
The iPhone Dev Team says that iPhone 3GS users with older bootrom should not use PwnageTool if they want to update to iOS 4.2.1, instead they should use the upcoming redsn0w release to update baseband firmware.

Redsn0w 0.9.6b4 works to jailbreak iOS 4.2.1, but for many devices it remains a tethered jailbreak. A tethered jailbreak means that you have to connect the iPhone or iPod touch to your computer and run redsn0w every time the device reboots or runs out of battery. Only the iPhone 3G, older iPhone 3GS, and older iPod touch 2G will work untethered with redsn0w. I would recommend most users wait for an untethered jailbreak since it will be easier in the longrun, but if you’re determined to jailbreak the latest iOS, here’s how:
