    I was told by AT&T to restore the device to complete the unlocking process. When I try to restore in iTunes, I'm informed that iTunes will restore and upgrade my iPhone to iOS 4.2.

    I've read everywhere that iOS > 4.0 slows up iPhone 3G. So, I'd like to:

    1. Restore my phone and get it unlocked.

    2. Run iOS 3.1.3.

    Will following this guide accomplish my above goals?[s]-from-ios-4-to-ios-313

    If not, could the experts here please advise on how I should go about doing it? I'd really appreciate any input on this.

    Thanks a ton in advance.

    Yes you can restore your 3G to 3.1.3 freely.

    The bummer with 3.1.3 vs 4.2 are all the unsupported apps you can't use.

    Thanks braddick

    I rarely use a few apps on the phone and most of them I had earlier work perfectly now.

    I'd trade anything for a faster GUI..

    I agree.
    You're better off with 3.1.3 on an iphone 3G.
    Anything above that then it becomes a turtle.
