    Sorry if this has been covered before :rolleyes:


    Im currently using my 3g which was purchased back in july 08 with 3.0 beta.


    Im looking to get the 3GS though next week.

    Id like to before i sell the 3G to downgrade to 2.0 firmware and jailbreak unlock as i think ill get more for it with it being unlocked.

    Ive not jailbroken the 3G i have now and only jailbroke my 2g a few years back.


    Can anyone tell me the best way to downgrade and what tools i need to jailbreak and unlock it before i chuck it on ebay?


    Thanks

    Put it into DFU Mode and do the downgrade.

    You can jailbreak it with Pwnage Tool. Then you need to unlock it with Yelowsn0w. :)

    There are a few things you need to do.

    1. Downgrade to 2.2.1
    2. Jailbreak with Quickpwn (Pwnage Tool doesn't support 2.2.1)
    3. Install 3G Fuzzyband Downgrader
    4. If you have 5.08 bootloader, then it will downgrade your baseband to 2.28.
    5. Install yellowsn0w.

    If your bootloader is not 5.08, then you cannot unlock your phone.
