>>so would i be ok in saying that you dont need webmessenger for AOL chat....because you have the IP stack...?
WebMessenger is separate from the IP stack. The IP stack is the thing that "enables" the Internet on your BlackBerry that WebMessenger requires. Some people need to purchase BES/MDS hosting in order to enable IP stack, but the elimination of this requirement that Nextel has an advantage. It's the BES/MDS hosting that you don't need with Nextel.
If you want to chat, then you do indeed still need a chat program such as WebMessenger or one of the several others.
But WebMessenger won't work if your BlackBerry does not have Internet capability. (BlackBerry needs a method of Internet connectivity -- such as Nextel TCP/IP, or Public MDS, or hosted MDS, or BlackBerryOS 3.8+ running on BWC 4.0)
