Sprint's the largest provider with Uncapped data now, also I've seen ads for MetroPCS $50/mo unlimited.
I pay $80/mo with a 2-yr Sprint contract for 4G (Motorola Photon). The 3g reception is very good (I've had 5 bars when my Verizon coworkers had 3).
If you're looking into 4g, the 4g coverage is pretty dismal in the city, and it's worse everywhere else. I get coverage within the square spanning 50-42st 10-8ave, but the speed there is really good (I can usually dl a show on my walk to work). 4g's basically nonexistent outside of NYC and other major cities
afaik, but should be expanding. I'm guessing there are other patches of 4g around manhattan, but I haven't walked around the city much yet.
I used 15gb data in August and like 8 in Sept. Don't know how you guys can live on 2gb.
