I won an iPhone on ebay the other and while I am wait for it to arrive I was searching around for was to unlock and jailbreak it. I have had an Ipod touch for about a year now but it has its limitations. I have done the jail break back when the firmware version was 1.1.2 through 1.1.4, but I haven’t dealt with the verson 2.0+ firmware. I ended up buying a non-3g 4gb iPhone. I have a 3g iPhone for work but I didn’t want to rely on that for doing unlocking projects. This method is not for the 3g model. It will not work because of some hardware differences. After searching around I found what looks like to be the easiest solution ever.
So basically Someone has created a firmware version that has already been jailbroken/unlocked so all you need to do is restore you phone with that firmware version. It’s a 250mb file so it is split into 3 chunks. Here are the links for the download.

Once you have those files unrar them and you should have your firmware version. Now plug in your iPhone and try to restore it. When it gives you the “restore” button hold shift while clicking it and it will give you and option to specify the firmware version you would like to load. Select the one you just un-rared and let it install. After it’s done installing you should have a fully unlocked and jailbroken iPhone. I have not tried this since I do not have the phone yet but it seems pretty easy.
