I'm only < 24 hours into it but Ting.com beta program phone showed up today. I get 500Mb per month for US$13 which is more than the ~250Mb I usually use. I'll get a credit back on the next month's bill which is, well, how it should be.

The bands are 100Mb = $3pm; 500Mb = $13; 1,000Mb = $24; 2,000Mb = $42; and 3,000Mb = $60.

I use zero voice minutes and zero text messages per month so my bill will be $19 (data + $6 per 'line') plus the usual mandatory taxes. This will save me about $60pm on my iPhone bill where I had no choice but to have voice.

They're a Sprint MVNO, there's no contract, and I have high hopes as the customer service has been outstanding to date. The Web-based management GUI is a bit spartan but that'll evolve over time I suppose. I only wish they were GSM-based instead of CDMA.
