Hello, I have an iPhone 2G that was purchased earlier this year and I never activated it; I unlocked and jailbroke it instead and everything has been fine so far. Last week I got a new iPhone 3G on O2-UK by renewing my contract. What I am trying to do now is to legitimately activate the 2G phone with a pay & go card, in order to give it as a gift to my sister. The thing is that when I try to activate it through iTunes, I get an error message saying this phone cannot be activated. I can always unlock and jailbreak it again, but I would like to take advantage of the legit activation since it is (or at least should be) still under warranty and since it did present some battery issues, I could be eligible for a replacement as I was told at Apple store. Does anyone know what my options are at this point? Many thanks and happy New Year to everyone.
