    If you go to SETTINGS -> GENERAL -> ABOUT, what is you Base Band version (MODEM FIRMWARE) in iOS5 and in iOS4?

    Because when you go from iOS4 to iOS 5 version, you probably are upgrading also the baseband from the 05.14.02 version to the 05.16.05 version.

    There are many people claiming that the newer baseband makes the GPS stop working!

    Try downloading RedSn0w latest version and try to upgrade to iOS5 but preserving the baseband!

    If you upgrade you BaseBand and then try to downgrade, since you have the NEW BOOTROM, be carefull! You can BRICK you iPhone!
