For the longest time, Twitter has seemingly been dominated by BlackBerry and iPhone users. Since there are a ton of Twitter clients available for BlackBerry, I was interested to see what everyone is using. Personally, my favorite is SocialScope, by far. The problem with SocialScope though, is the availability of it. It is only accessible by invite since it is still in private beta. The development started very fast for it, but sloped off rather quickly. It has come leaps and bounds from the original beta release, but without everyone being able to use it, it is probably one of the most under-appreciated clients by the majority. It’s packed with more features than any of the other clients, and doesn’t just stop at Twitter. It supports FourSquare (I wonder how long it will be before it supports Gowalla), Facebook, and Flickr.
