BES v4.1 SP5I just received the IT Edition of the BlackBerry Newsletter, and for those of you interested in the BES side of the BlackBerry world there is lots of info on the Newly Announced BlackBerry Enterprise Server v4.1 Service Pack 5. Be sure to check out the Feature Overview .

There's also advertising for two webinars coming up on Feb. 20th and 21st, respectively: BES v4.1SP5 for Lotus Domino and BES v4.1SP5 for Microsoft Exchange.

This is great news for those in the BES environment - it has been a long time coming. But of course, I'm a BIS customer these days so all I'm really concerned about is the release of the BlackBerry Operating System version 4.5 updates!
