    So I am having an issue with Yellowsn0w. When I install yellowsn0w my AT&T sim card won't work. When I try to make a call my signal craps out. This also happens with incoming calls as well as text and data. Once I uninstall Yellowsn0w everything goes back to normal. I'm not sure what I am doing wrong. Also, my T-mobile US sim card (Pay as you go) doesn't work as well. It always shows as an 'invalid sim.' But, I think that is happening to everyone.

    Thanks for the help,


    oh, I am using a 16GB black 3g iphone.

    Yep me too-I have a Rogers PPD I use, and 0.9.5 actually allowed me to make outgoing calls with Rogers SIM.

    However, put AT$T back in and now can't stay connected to my wife's locked but JB iPhone. Can talk for 5-10 seconds and then the call fails.

    This happens even after I removed yellowsn0w so now I am doing a whole new 2.2 install. I sure hope that resolves the problem...
