I'm one of the unlucky ones who got "no signal" on their 3.0 iPhone 3G :( It's been 6 days since ultrasnow got released, and after doing everything I could, I decided to go back to 2.2.1 ..
Can someone please tell me what do I have to do, in order to downgrade my iPhone ?? Should I just make a custom 2.2.1 firmware and restore the phone, or will there be problems ??
