    Install the OS using Desktop Manager. If it still doesn't work, install a clean OS.

    IF you keep getting invalid sim, you might just have a bad sim card. Take the phone in and get a new one. (Sim card, not phone)

    No, i had the same issue when i first got my 8530, and i went through 2 in 3 days. It is not the OS or the sim card. A OS reinstall or upgrade will not help at all if anything it will make it worse.
    Even the techs at sprint couldn't figure it out.
    So to make a long story short,, the software is bad and you need a new phone. take it back to the service center and they will hook you up.

    I tend to disagree. There has been a few flaws with the 8530 CDMA software coming out, as the above poster states. However the 8520 GSM software versions have not been having these issues. I had the exact same issue that the OP stated. My sim card went bad and I needed a new one. Had nothing to do with the OS.

    As you troubleshoot you need to eliminate the obvious. Try the sim card first.
