TwitterBerry, “… is mobile client for posting updates to Twitter. It works over the data network, so you don’t need to use SMS. ” (Source: http://orangatame.com/products/twitterberry/, retrieved Feburary 25, 2009). For those of you Twitter Fanatics like me, you may want to check it out. I installed it on my Blackberry 8300 today and did a tweet on it with no problems at all.
