AIM application came preinstalled on the phone, but it's a mobile version (only allows 30 contacts, doesn't allow you to see away messages). Is there an expanded version that anybody knows of? Thanks in advance!
However, you can remove all those preloaded IM clients and install just one that will do everything. Try JiveTalk. It's $29 (one time fee.) You can get a 30 day trial. It's the most preferred IM client out there for BB.
