As my last thread was closed as Hutch deemed it was a classified advert rather than a request for assistance, does anyone know where I can get software to allow, in the simplest way, to upgrade a JB/unlocked 2g from 2.2.1 to 3.1.2? I dont have a Mac but am looking for a simple method as phones aren't my forte.

I did my 3G from 3.0 to 3.12 with these custom firmware.

You will need the iPhone 2G 3.1 Custom Firmware Activated for Other Carriers Part 1 and Part 2 and the tool to join them.Its easier than it looks and all the instructions are there to walk you through the process just in case you dont find anyone local and want to give it a go yourself.

Just wanted to add quickest way for me was to update then run blackra1n
but after bootneuter was run i had to install the patched lockdown file otherwise i could not use any other sim.

anybody who gets the sim card invalid message
just holla if you want the info
i thought 2G to be easiest jailbreak & unlock Iphone3G is the easiet since Blackra1n came on the scene
