Have I bricked my iphone ?

[GOODTINGSaka]

yesterday i decided to take the leap and upgrade my 11.4 unlocked iphone to 2.0 ( something im regretting now ) well i upgraded the phone to 2.0 fine only to find that its now sim locked again so i thought ok il use pawnage after the upgrade . followed the instructions on a previous thread to the t only to find it was now showing no signal reception.
now i dont know if this is where i went wrong so i tried it again now the phone wont restore either with pawnage or with itunes it comes up with error 1604 i have tried it on 3 diffrent machines and still cant get it to work. so the question is have i killed it or is there hope ?

ok people i have fixed it i restored it on the apple mac mini i got here somehow it restored back to 11.4 so i just restored and jail broke it and thats where its gonna stay till theres a real fool proof way of upgrading and unlocking 2.0

Rumours of an unlock of 3G 2.0 with yessim , but I have my doubts

dont worry you havent bricked it.

When you created the new firmware you needed to unselect the activate iphone. thats why you got the problem with no service.

follow this guide step by step to make it easy.
