    Ive taken the plunge - upgraded to the iPhone4 - its great - im in UK on O2.
    I followed the transferring your sim to the new micro sim instructions - it all worked well overnight - and my new phone is fantastic.

    however ive just realised i should probably have asked o2 to unlock my old phone (which apparently they would do for free as i was at end of contract) before transferring the sim.

    so my question is id like to give my old phone to my son - who has a vodafone payg sim - can i easily - legally unlock the iPhone3G for him?

    i realise i can enter the dark world of jailbreaking but im not that keen to do that unless i have to.

    i can just order a o2 payg sim - and i suppose this is my default fall back but as he has credit on the sim he has - hed like to use that for now.

    any ideas? help appreciated?

    You don't need a SIM to physically be in the phone you want to unlock, you only need an eligible SIM card (your current SIM). Just enter your details online and they'll send a text to you regardless of which phone your SIM is in. Then you just pop any non-O2 SIM into your old 3G, connect to iTunes and the rest as they say is history.

    Remember don't upgrade your 3G to iOS4 if you don't want to cripple it ;)

    Ok thanks. Will give it a go. Have just submitted my IMEI code for the old phone to O2.

    Alas i made that mistake - one of the reasons i bought an iPhone4 - though bizarrely - potentially everyones happy - i have a new iphone4 - my son has my iphone3 if only the his sim worked (hopefully) though he is left with a slow buggy iphone. I'm toying with downgrading him - there seem to be some posts it can be done from iTunes? or waiting for 4.1 - he actually doesnt need the phone functionality until school goes back so as long as 4.1 comes out soon he should be ok.

    Just to state that the advice worked. I downgraded and unlocked and my son is very happy!
