Word just got out of a webinar showing off the newest BlackBerry Enterprise Server service pack, featuring all the good stuff we’ve been looking forward to in OS 4.5, such as full HTML e-mail viewing and remote e-mail lookup. Of course, this is all the same stuff we’ve been seeing since WES ’07, but who knows, maybe this is signaling an impending release. Even then, we’ll still have to wait for the handheld software to follow up before we can start seeing all these new features. The webinar is taking place Feb 21st., from 12 PM – 1PM EST for the Exchange presentation, and Feb. 20th. at the same time for the Lotus Domino presentation.
