    Ive been digging around in my settings, but I can't seem to find what I'm looking for. Can anyone offer me some insight as to how I can do this?

    I've wondered this too, and searched around online for it. All I can figure is the iPhone automatically checks in the background every-so-often, since iTunes didn't offer to update any carrier settings.

    If you go to Settings > General > About, then down to Carrier, it'll say Sprint - Tap on Sprint to cycle though your PRL and ERI.

    My PRL is: 51082
    My ERI is: 1

    Go to the phone app, go to the dialpad and type in:


    This will do a Sprint system update.
