But to be honest with you why would you want to on the Edge network. It's slower than dial up!! Get a phone that supports 3G like the Tilt for instance. You're websurfing will be much more enjoyable.

its included...the point of the phone is to surf the internet so it comes with unlimited internet use. The cheapest service plan is $55 and thats with 450 mins, and thats with unlimited internet and email.
