ATTENTION ALL CINGULAR USERS OF THE 8700c:
In order to get the web messenger clients and chat services to work, such as AIM, Yahoo Messenger, & MSN, etc. you have to call cingular and ask to have the data connect services added to your plan on top of the Blackberry Unlimited Connect Service. The data connect is a free add-on once you have the Blackberry Unlimited. Just explain to them that you want to be able to use the messenging clients and the customer service agent will assist you. The Data connect opens up the WAP port so you can connect to those services.
DONT ASK FOR WAP FEATURE ASK FOR THE DATA CONNECT ADD ON

1. Go to Settings
2. click > Options
3. click > Advanced Options
