We have always been a fan of third party instant messaging apps for BlackBerry. We have seen JiveTalk and IM+ become big hits. BBcool just got wind of a new one called Palringo, which has introduced a new multi account IM program for BlackBerry smartphones.
Palringo is a free over the air download to your BlackBerry and has support for Windows Live, Yahoo!, AIM, ICQ, Google Talk, Jabber and a few others. You can download it OTA by clicking here from your mobile phone.
