Today EQO Communications announced support for RIM Blackberry and Windows Mobile devices, allowing EQO’s VoIP calling and IM services to be extended to these platforms. EQO supports all of the major IM systems (AIM, ICQ, GoogleTalk, Jabber, MSN, Yahoo! and Skype). While EQO had previously focused on bringing IM and VoIP to more common and inexpensive cellular handsets, this move really makes sense as smartphones with full keyboards, and which are often bundled with wireless data services, are a natural fit for IM. Having just joined the ranks of Blackberry users myself, I’ll definitely be giving the EQO Mobile services a spin on that platform.
