New USA T-mobile iPhone user w/ a question

[icanhasiphone?]

I just got my first iPhone yesterday :) (2G in perfect condition). It's unlocked for use on T-mobile but i have no idea what T-mobile Internet plan to sign up for so I can use the iPhone on the EDGE network. Can anyone who is using the iPhone with T-mobile help me out? Thanks!

You can sign up for the 9.99 Web to go plan but it's capped out at 50mb but includes 200 text messages. Just use that plan for right now and wait until June 3rd when T-Mobile launches Web2Go unlimited for 9.99 without text messages.
