BlackBerry IP-Relay should be easier to use than AOL AIM -- it is real time -- keypress-at-a-time -- splitscreen chat window like
www.ip-relay.com! Except no hitting Enter like for AOL AIM.
Unfortunately, Sprint BlackBerry is not currently compatible with IP-Relay unless you have BES. If your BlackBerry was provided by your work, you may be in luck --
just try the BES version by typing "http://ip-relay.idokorro.com/IPRelayBES.jad" into your BlackBerry Web Browser.
If your BlackBerry was directly purchased by you and you are on T-Mobile, Nextel or AT&T, then just follow MCI's instructions instead at
www.ip-relay.com (Verizon model 7250 users, just simply follow the instructions for Nextel users.)
