oh i still dont understand why you had to be on itunes 9..

[vVvTutorialsvVv]

@MrDomezy It had to be on iTunes 9 so that it will be able to downgrade.

[MrDomezy]

What happens if you just restore using the stock 4.1 ipsw and not the sn0wbreeze restore?

[vVvTutorialsvVv]

@MrDomezy It will not let you. The stock firmware does not have the iPad Baseband.

[bhagatking22]

@Bruno8423 maybe update your itunes version

[SuperLedsabbath]

and the baseband does still being the same or it does changes cause you did not show that on the video?>??

[MrApadkukar]

this method wil fix GPS problems ?

[Bruno8423]

Now when I open the Itunes with the phone in DFU mode apeers "The Iphone software update server could not be contacted" what I have to do?

[vVvTutorialsvVv]

@Bruno8423 Sry to say this but i dont know what to do ive never had that problem.

[Bruno8423]

But when you put the Iphone in DFU mode the Iphone was plugged.

[Bruno8423]

When I plug the Iphone 3g to the computer the Itunes opens and says "Iphone cannot be used because it requires iTunes version 10.1 or later" what I have to do??

Please help me!!

[vVvTutorialsvVv]

@Bruno8423 you can only plug it in when its in the deep DFU mode
