I installed the ipad baseband (6.15.00) a few months ago to unlock my iphone 3gs which is currently running ios 4.1. I knew it would disable my location services and therefore disable my GPS.
Today I downgraded my baseband to 5.13.04 using the newest version of redsn0w. It was supposed to fix my location services/GPS but it is still greyed out, what can I do?
I tried reinstalling mobile substrate and ultrasn0w using cydia but that didn't work. Would I have to reinstall/update my ios?
