I have a 3gs stuck on iOS 4.1, but with 9A405 baseband. I want to upgrade my phone to iOS 5.0 or 5.0.1, but every time I try I receive the requested build error or error 3002. I already tried changing my hosts, upgrading to different firmware, used tinyumbrella, used redsn0w, restoring to different firmwares with and without DFU mode. Im running a mac too and have the most updated version of iTunes and OS X.
