I found a great iPhone software called Unlocker, which will unlock iPhones and iPods unlimited. iPhone Unlocker is designed with the best development and is designed with simplicity in mind. Once you download this software, your iPhone will be unlocked and ready to use on any network worldwide in minutes without any technical knowledge required.
Connect your iPhone to your computer, select the options and right click on Free my iPhone to unlock the phone. All 1.1.3 versions, including support! (Only supported on jailbroken iPod Touch)
