So this morning, can't pick up anything. 4150L is deader than a doorknob. Rebooted, pulled battery - you name it. Doesn't matter. This particular behavior doesn't happen often but it's also not rare. Just another wonderful "feature" of this device. Absolutely incredible how poor this thing is. Legal intricacies aside, Verizon ought to be penalized to within an inch of corporate life for this thing.
