This comes in as a BIG rumor but we wanted to roll with it, just in case ;)  Seems as though an informant was able to get some juicy news on the RIM official twitter client.  Rumor has it that the client will launch in App World on March 4th.  Now, I stress again, this is a RUMOR right now but we are working on more confirmation.  As soon as we get it we will update the post.
