RIM has updated their OS usage statistics using February data. Unlike last time they broke out the number of users on OS 6. These official numbers look very close to what I reported for February. For OS 6.0 RIM reports 20% while I saw 19.6%. For OS 5.0+ RIM reports 81%, while I see 80.6%. Additionally we both see almost no users on OS 4.7.0 and 4.7.1.
