Can i do this? Is there a guide for it? If i do it, do i have to repeat unlock of the 1.1.1?

Desperate!

all you will have to repeat is the activtion process with let's say independecne for example... you will not have to unlock again

Ive unlocked mine with jailbreakme.com and anySIM 1.1, Phone is out of box 1.1.1. But im having some issues with calling (call failed) and i would like to restore it completely and go thru all again.

Thanks in advise

I had a similar situation - unlocked with anySIM1.1, activated with touchfree. Phone seemed unlocked but wouldn't pick up a signal. I restored. Unlock survived the restore and I was able to make calls after I jailbraked/activated with the dev team method. Now I've restored several phones that I jailbreaked/activated with the dev team method so I could use the jailbreakme.com method. Again, anySIM1.1 survived the restore. It even survives moving back and forth between 1.0.2 firmware and 1.1.1 (of course activation/jailbreak needs to be redone).

Huh, so even downgrading wont restore it to factory setup? I would really need to restore it completely coz i wont to go thru whole process again. Jailbreak and anysim.

You have to downgrade to 1.0.2 using the DFU mode and then upgrade again using independence.
