i have a hardware unlocked 1.1.2 iphone, updated recently to 1.1.3
but i have a horrible reception, and calls keep dropping
no one seem to know a solution for the problem,
i'm suspecting a conflict between the bootloader and its current firmware
originally it should be running a 4.6, but the h/w unlock runs it on 3.9
i'm out of tricks, so i thought i would give it a try
since now that the software unlock is out

my question is, how do i update my bootloader to 4.6?
in a way, to virginize all the unlocking i've done

appreciate any help
