Appletell reviews Twitterrific for iPhone

Twitter, the micro-blogging site where you can upload posts of just 140 characters, is designed for the mobile. In fact, it’s built around the SMS, with the idea that people could answer the question “What are you doing?” from any cell phone or web connection. Twitterrific from the Iconfactory gives access to most of the popular features in a simple, easy-to-understand interface. It comes in two versions, plain (free) and premium, which are identical, except that once per hour the free version displays a small ad.
