    You likely do not have an unlock problem but an activation one.

    My recommended path.

    Jailbreak with blackra1n
    Restore a custom ipsw made using pwnagetool 3.1.4 using iTunes.

    The first step should get you an activated iPhone that you can make/recieve calls with. Then the second step should fix Location Services, YouTube and allow tools like DiskAid and iPhone Browser to work.

    Blackra1n does not need any interaction with iTunes to jailbreak. In fact it works best if you connect the iPhone, wait for iTunes to start, shut iTunes down and then use task manager/activity monitor to search for iTunes helper and shut that down too.

    Then run blackra1n RC3, it will detect your iPhone and jailbreak it, as part of jailbreaking it will hacktivate it (thus bypassing the iTunes error you have now)

    Look at the following guide: for more details.
    Jailbreak Unlock iPhone 2G 3.1.2 With Blackra1n Windows Mac | iPhone

    You only need the boot neuter step if after jailbreak your still can't get network coverage and make/receive calls.

    No need to downgrade, you need to make a custom IPCC bundle and upload it to your iPhone. See http://www.hackint0sh.org/f127/78031.htm for details.

    Please take a good look around the forums. There are solutions to nearly everything you want to enable on a 2G iPhone running 3.1.2 (including tethering, stereo bluetooth and MMS)
