iPhone downgrade to OS 2.2.1 (from 3.0 beta 3) AND w/ baseband 04.20.01
I've been stuck here for the last few weeks. I was stupid enough to upgrade my iphone to OS 3.0 beta 3 and successfully downgraded to OS 2.1.1. However, my baseband is the latest one which is 04.20.01. All features work with the Iphone however I cannot send/receive calls or SMS. I understand that downgrading baseband from 04.20.01 does not exist (let me know if I'm wrong here). Is there any way for me to get SMS/calls working with this baseband on OS 2.1.1?
Let's just say worst case scenario that I can't.. will the official OS 3.0 release fix this issue? I'm hoping that my iphone isn't bricked for life... :(
Please help me out. Many thanks to those that reply.
