  14. Hi all.

    I have almost the same problem as Sara here.
    I HAVE had my 3G 2.2.1 Modem2.30.03 jailbroken BUT it still says Invalid SIM when I try to put my Orange UK SIM in.
    I installed Cydia but don’t know how to use it???

    Is there anyone that could explain to me (as if I was a retard) how to unlock my 3G 2.2.1 to work with any SIM card.

    I do not have a o2 SIM card to put in the phone.

    I would be VERY VERY greatfull if someone could help me with this…

    Thanks in advance.

  15. Hello everyone.

    Could someone please help me out.
    I am currently on 2.2.1 with 02.28.00.
    I would like to upgrade to 3.0.1.
    Now here is the question:
    Can I upgrade and still keep the 02.28.00 to have it unlocked for any SIM card or would it become locked again???
    I have heard that someone upgraded the 02.28.00 to 4. something and then used ultrasn0w 0.9, would this work?

    How should i go around this one?

    Thanks in advance.

    Henius.
