BeejiveIM

The BeejiveIM is a user-friendly mobile IM application available for the Blackberry, iPhone, iPod Touch, and Windows Mobile. Its Blackberry version offers the most features; but it is in fact the iPhone version that has garnered the most interest.

Once downloaded, users can stay connected to all their IM buddies on all their instant-messaging accounts, including: AIM, iChat, MobileMe, MSN, Windows Live, Yahoo, Facebook, Myspace, GoogleTalk, ICQ, and Jabber. Signature to BeejiveIM is that once downloaded, it becomes 100% free to send instant messages — as there are in fact zero SMS charges. Plus, all the regular IM features still apply: manage buddy list, add/remove friends, block people, be invisible, set an auto-away message, and incorporate a buddy icon.
