    iirc, it should be a matter of restoring with the 2.0.2 file with itunes. you may need the itunes 7.7 if you updated yours to 8. hopefully some experts or someone who has downgraded 2.1 -> 2.0.2 can chime in.

    but basically, put your phone in dfu mode(search youtube or here) while plugging in and with itunes running, click the restore button on itunes while holding down the shift key and browse to the appropriate restore file below.

    1st gen firmware

    2nd gen firmware (3g)

    yeah, next time, please provide which iphone, itunes version, and anything else we may need to know. helps us helping you better.;)

    Try to restore 2.1

    Downgrading to previous FW is not always an option. Basically, if modem software was updated you would not be able to go back to previous version. Old 2G phones are different (possible to downgrade), some folks assume 3G is the same, but it is not.

    Give it a full restore in DFU mode and you should be fine. (search forum for DFU)

    I have Zero issues with 2.1, why should you? I upgraded last Friday night. Battery is still at 85%. 3G speed test was a bit faster.
