I've thought about dumping cable and using the phone - according to Comcast one month we used 105 gigs! - seriously over 'normal' for us -
does you phone connection get slowed down after some limit is reached?
with the iPhone I can use either USB tether or set up a wireless hotspot. we use it when traveling or when the cable goes out.
20 gigs??I, also, have mobile hot spot through Boost Mobile.
Eight gigs was not enough, so I changed to 20 gigs. Unlimited data!!
