I just got a new windows mobile 6 based phone (HTC Mogul 6800) and naturally I added the sprint data package to my phone for $15 per month. I then asked them about tethering the phone as a modem with my laptop and i was informed it would cost an extra $40 for that ability. Screw that. I wouldn't use it enough to justify that cost, considering my bill is already around $150 a month.
