I have a blackberry 8320 curve from t-mobile. I do not have a data plan. I am able to get online with the Wi-Fi Feature but i cannot use online apps such as AIM, Yahoo messenger, and others. Is there a way i can change that so it uses the Wi-Fi connection as well? thank you very much

Many of the chat programs require a data plan.

Look at the thread in our WiFi section about this matter:

and other threads there.
