Unlocked Shadow on AT&T - internet conntection

[Guest scka101]

I have an unlocked Shadow that I am using w/ AT&T. My question deals with the internet and its connection. I don't have a data plan but I do have wifi at my house. Even though I don't have a data plan I can still connect to the internet and get charged by the data usage. I want to know how to make sure I'm surfing via wifi and not the AT&T internet option. I don't want to get my bill and find out I've been using AT&T connection, and not my wifi. Any help?

Two simplest solutions:

1. Contact ATT customer service, and have them disable pay per use internet.

or

2. Delete the GPRS and Proxy connection settings for ATT.
