If you have a jailbroken 1.1.1 or 1.1.2 iPhone or iPod Touch, you can now upgrade to the newest 1.1.3 firmware directly from the “Installer.app”. Over a broadband connection the upgrade takes anywhere from 10-45 minutes so you will most likely want to have it plugged in. To perform the upgrade you will have to have a previously jailbroken device and the “Installer.app” on your device. This upgrade should not be performed on unlocked 1.1.(x) phones as there is no unlock solution for 1.1.3 iPhones.
