UPgrade iPhone baseband

[Louis54000]

Hi everybody, I've got a problem : I upgraded my iPhone 3G to iPad 06.15.00 baseband In order to hacktivate it. But now, I don't need to be hacktivated, because it is now legally unlocked so I restored it ( to 4.1 because 4.2.1 was freezing on restore mode, I tried everything (tiny umbrella etc)) and I'm still on 06.15.00 baseband. So now, I'd like to upgrade the baseband to get a true iPhone one, the iPad one consumes a lot of battery, and make my iPhone heat. I don't need an unlockable baseband. Just return to a true iPhone baseband and ge my gps back.
Thanks for your answers!!!
Please help me!

Unfortunately... once you've installed the iPad Baseband there is no way to move on to another BB. Sorry
