Unlock the iPhone 3GS yourself for free

If you have an iPhone 3GS it is pretty easy to unlock for free. It involves a process known as jailbreaking (opening up the software on your phone) and then running some additional software to perform the actual unlock.

The first thing to do is to check that there is an available unlock for the version of iOS and baseband (modem firmware) that you are using, or that there is a downgrade to a supported baseband. To check your iOS version and baseband, go to Settings > General > About on your iPhone.

At the time of writing the latest version of iOS with an available untethered jailbreak and unlock is 5.1.1 (using ultrasn0w 1.2.7) providing you are on one of the following baseband 

Supported versions

iPhone 4: 01.59.00
iPhone 3G(S): 04.26.08, 05.11.07, 05.13.04, 05.12.01, 06.15.00*

Once ultrasn0w 1.2.8 is released, a jailbreak and unlock will be available on iOS 6.x on the same basebands listed above. Check the iPhone Dev Blog for updates.

Redsn0w is available from the iPhone Dev Blog

Ultrasn0w is available on Cydia by adding to the list of sources.

* Baseband 06.15.00 is an iPad baseband, and disables the GPS receiver. If you have already updated to 06.15.00 to unlock, there is a baseband downgrade available using redsn0w (0.9.15b1). If you are going to downgrade, you must make sure that you have a compatible model iPhone 3G(s), as newer models have a fixed baseband. Follow the instructions on redsn0w very carefully

*Please note prices to unlock may vary according to which network you’re currently with.
