Twitter has realized that mobile is the place to be and has been pushing out mobile clients to all the major platforms over the course of this year. Twitter launched its Twitter for BlackBerry app as a private beta in February and rolled out the official app in July. Unlike the other mobile platforms which were developed by Twitter independently (Android) or via acquisition (iPhone), the Twitter for BlackBerry app was developed in conjunction with RIM. Soon there after, Twitter took on the Android powerhouses of Twydroid and Seesmic when it launched the official Twitter for Android back in April of this year. Last but not least, it acquired Tweetie and rolled out the official Twitter for iPhone in May. INTOMOBILE
