I'm not a heavy mobile phone user at all - maybe a couple hundred minutes and about 10-20 texts a month - but I want to get a smartphone for internet access, email, IM, maps etc. I'm located in the New York City area, and not under contract right now so my options are wide open. I'd like a good quality, functional phone, but I don't want to pay the huge monthly bill an iPhone or Pre requires. Since having lots of useful features is far more important to me than unlimited talk or text, I'm willing to spend a bit more for the phone upfront (particularly if I can get it contract-free), but want to know: who has the absolute cheapest monthly plan which includes data access?
