    I have an iPhone3GS running 3.1.3 and last night I used Spirit to jailbreak the phone. The jailbreaking process went fine and i was able to use cydia and install things from it and there were no issues with 3G service at all.

    Now this morning after charging my phone through the night, I am not able to get any signal with the phone and it either says "No Service" in the top left corner or it has 1 bar of Edge service but i still cannot text, call, or use data. Every time I try to call or send messages I get the notification that says: "Cannot Activate Cellular Data Network." Normally in my house I get full 5 bars of 3G service so I know it isn't my location, it has to be something with the jailbreak.

    Has anyone else had this problem with the Spirit jailbreak and offer a way to fix it? I would really like to keep the jailbreak because it adds tons of functionality that I would lose if I restore. Any help would be greatly appreciated, thanks.

    At the iPhone hacks section.
    You guys activated the phone with a valid simcard before running spirit on the 3.1.3 right?

    What did you install from Cydia?

    Was there anything related to unlocking etc. If so that may be your root cause. I do not think the spirit JB would be to blame.
