Downgrading 4.3 to 4.2.1

Is this possible?

Would it cause problems since the baseband would be higher.

I understand it has to be done in DFU mode, but any input would be nice

Since Apple is still signing 4.2.1, just downgrade. You don't even need any special steps.

Are you sure?

It dumped by phone into recovery mode doing it the "normal" way, guessing DFU is the only way since it bypasses the version check (IIRC)

Downgrading due to constant cell chatter (making speakers buzz every 5 minutes) and usage and data creeping up in standby, my iPhone didn't do this on 4.2.1.

This might become a widespread problem after the 11th, but going back to 4.2.1 ASAP

Are you a developer or not? If you are, there's a nice thread on the dev forums.

Nope, what is the thread about? Downgrading or bugs?

Either way, it seems to be downgrading now 🙂
 
You mustn't forget that the baseband was upgraded and won't be downgraded even if you go back to 4.2.1 and given that your problems are network related i doubt your issues will disappear since you'd still be sporting the new baseband post downgrade.
