    First off sorry if this has been posted, I tried to post it on my iPhone before but don't think it worked.

    To cut a long story short, I sold my 3G on ebay. The buyer has requested me to keep 2.2.1 on so he can unlock it. Can i upgrade to 3.0 then downgrade before I post it? I don't know much about this unlocking business.

    My worry is I have heard that once you download 3.0 you can't go back to a earlier firmware. Also even if you can, by putting 3.0 on my phone could it do anything that would stop it being unlocked? Even if i did go back to 2.2.1?

    Help would be appreciated.

    I know that with the 3.0 Gold Master you can't revert back to 2.2.1. I'm not certain about the official 3.0 being released today.

    No. It won't work mate. I'm 99.9% sure.

    Not worth the risk.

    Why take the chance?

    I think you are better off leaving it as is.

    Just my $0.02.

    You will be able to unlock 3.0 once it is officially released.

    Just update it and tell the buyer that 3.0 will be unlockable on Friday.

    Why go and update it if you're selling it? Buyer's made a specific request to keep 2.2.1 i.e. don't update.

    Just leave it 2.2.1 mate. 3.0 is nothing revolutionary.

    I think you should leave the phone as is. The buyer is buying the phone with the expectation that it will have 2.2.1 and not 3.0.

    My understanding is this:

    1. Yes you can roll back from 3.0 to 2.2.1 but no you cannot roll back the baseband.

    2. Yes 3.0 can be unlocked - check the dev team blog.

    3. Why the hell would you upgrade a phone you have sold and the buyer has clearly asked you not too?

    Funny that he wanted it on 2.2.1 since that firmware version can't be unlocked :)
    Anyway, mail him and tell him 3.0 can be unlock this Friday. He'll probably thank you for it.
