[SOLVED] Iphone 2G 16 GB downgrade back to OS 3.0

Hi guys!

Please help me, i wanna know:

Im using an Iphone 2G 3.1.2..
I have upgraded it, and jailbreak with Blackra1n, and unlocked with Bootneuter.

Can i downgrade it back to 3.0 and use the Pwnage tool to jailbreak unlock?

Will there be complications?

I have found that 3.1.2 is buggy, sometimes calls does not come trough etc, and i have to reset my device.

Please comment, so that i know its safe to do so! Fanks from S Africa!

 

Cool

Guys

Im sorted!

I want to let everyone know, that it works.

I restored back to 3.0 and used the pwnage tool to jailbreak/ unlock again.

Device is 100%
