Is There Any Way to Downgrade iPad Baseband 06.15.00 on iPhone 3G?

Hi, this is Lucian from Bistrita, Romania. I have iPhone 3G jailbroken and unlocked on iOS 4.1 with baseband 06.15.00. Since then, i have used Ultrasn0w 1.2 to unlock my iPhone, its battery lasts for 6 to 7 hours only :( Previously my iPhone was on iOS 4.0 with 05.13.04 baseband and my iPhone battery never failed before 12 hours. Is there any way to revert back to 05.13.04 from 06.15.00 baseband?

Question asked by Lucian

I am afraid but there is no way to downgrade your iPhone 3G baseband from 06.15.00 to 05.13.04. However if you are facing battery or overheating issues after using Ultrasn0w 1.2 to unlock your iPhone, you must follow these steps proposed by Sherif Hashim to get over with these issues.

Update: According to the recent tweet by iPhone Dev-Team, soon you will be able to downgrade iPad baseband. Cheers!
