Unlocking Phones to use on ATT

I know that carriers use different networks. I have a regular data plan for ATT and do not want to buy the BB data plan. My question is if I get a Tmobile 9700 unlocked for use on ATT, will I be missing any features? I plan to use WiFi and download Opera to browse the internet. Will this all work okay? Thanks for your help.

You will need a Blackberry Data Plan in order to be able to use all features of the Blackberry such as browser, bbm, email etc...
