    Hello ladies and gent's

    The girlfriend finally decided to make the change to a smartphone so I decided to give her my old 3G as a trial to see how she likes it and how long she can go without breaking it lol. Then I'll pick her up an IP4 or something later on.

    But I was wonderif what the best route would be to JB her phone? It's a 3G (AT&T) running I believe 4.2.1 or whatever the most recent one is.

    I greatly appreciate any help or advice, if this has been asked over and over I sincerely apologize for asking yet again. Will continue to do some reading on these forums.

    Thanks in advance and everyone have a wonderful weekend!

    Green poison. Type that in google and you'll find it. It's "GreenPoison RC5 for 4.2.1"

    Though a Iphone 3g running ios 4 is a risk jailbreaking. It may become very unstable, laggy, and crash frequently, which in return she will come to hate iphones. Unless you can downgrade to ios 3, which is more stable when sustaining a jailbreak.

    Do as you wish though

    Sorry to ask questions you've probably heard many times before but is it possible to downgrade the firmware? How would I go about doing so?

    We both greatly appreciate all the help

    3.1.3 ?
    Would that be the better most stable choice over 4.2.1?
