I would go with alltel before Verizion takes over . They are one the the last company's out there that let you use your plan minutes for data and do not have a cap. I have never had any issues with them and I use them along with AT&T for data. If you are in a 3G area I would go with AT&T for faster upload speeds. I get 500 to 900 up on my data card and very good latency. Remember that with AT&T different devices have different data rights so phones and PDA's will not see the same speeds that a data card will see.
