Since y'all are talking about tethering and I saw the OP mentioned code "67" I figured I would finally ask about it. I have seen error 67 mentioned quite a few times and wondered what it pertains to as far as tethering goes. I am on Tmobile and have never had it myself so I am assuming it is a problem with Sprint? I am just curious cuz so far I haven't been able to figure out what it is on my own. Anyone care to explain it to me
