Hi it's Itunes 7.5 but put in a search on you tube and they will give you all the info you need including the work around to blank your baseband watch :[ame=http://uk.youtube.com/watch?v=OtYZrhPWrvA]YouTube - How to downgrade iphone 2.0 2.0.1 2.0.2 and 2.1 - 1.1.4 and fix error code 1015[/ame] and all will be revealed. I find you tube invaluable as it not only explains but shows you aswell all you have to do is watch it through first then start it up again and follow the directions step by step pausing the tape to do what you've seen then restart when ready. Hope this helps
