iPhone Techie

As you know Apple suggests to use iTunes’ automatic update process to upgrade your device, but you can also download the firmware directly to your computer first from apple — you should always do this if you’re trying to jailbreak or unlock your device, or if you know you will not be on line / connected later while you will need to update your device.

Below is a list of all currently available firmware versions for the original (2G) iPhone, the iPhone 3G, and the iPhone 3GS, from v1.0 to v3.1.0.

I would strongly recommend using Mozilla Firefox to download the firmware files. If you use Safari you will have to disable the auto unzip feature otherwise the Restore File will be downloaded as a Zip file
