Can a blackberry curve 8310 be used on a GoPhone Account?

I intend to purchase a Blackberry Curve 8310 at AT & T. The only reason I want this phone is for the keyboard. All I need to know, I will do in the situation, calls and text messages with this phone on my prepaid account. I do not care about access to the Internet, I just want the text to be simple and call people. For the answers!
