Robb over at RIMmarkable has found a hefty reference for anyone looking for a few new tricks on your BlackBerry. The guide categorizes some 616 alliance members’ software solutions, for easy lookup and information. After a quick sign-up, you can download the 273-meg behemoth, but for the lighter readers there’s a web-based viewer too. This is a great reference for anyone looking to fill a particular task with their BlackBerry. We tend to keep an eye on new ISV additions, but now you get to see ‘em all in the same place. You can find both the download and web viewer at RIM’s site.
