    I've got the 1st gen iPhone and it's bloody slow!

    Can I get it all the way back to the 1st OS?

    Something must be wrong. I have the first gen as well with 3.0 and it's faster than ever. I'm not sure what's wrong but it shouldn't be like that.

    Of course you can! its absolutely legal! just get your hands on an earlier restore ipsw file.

    Then shift+click restore in iTunes and select the old ipsw file to restore to an earlier OS.

    Beware though, most apps won't work, and if you are going back to 1.0 none but the default will.

    If I were you I would try to restore and start from scratch (wipe and restore from backup) with 2.2.1 or 3.0 GM because those should definitely be faster, even on a 2G iPhone.

    agreed, my 1st gen is running fine on 3.0 and has been for a month.

    actually they aren't at all....1.1.4 was the fastest and most stable iPhone OS to date. It can't do a lot on it compared to 2.2.1/3.0 but it was definitely the fastest/least crashy

    but i do agree you should try a 2.2.1 restore first before resorting back to 1.x

    You cannot easily downgrade firmwares of your iPhone this way.

    You need to have your iPhone in DFU mode before you can downgrade.

    To downgrade to earlier 1.xx firmwares you also must also use an older (7.x) version of iTunes.
