Just noticed this morning that BBM 5.0.0.56 is available for download from the Help site. Strangely though, while I thought this would solve my problem for the last two days, it doesn't. I cannot seem to send messages to my contacts while they can message me just fine. I tested it with my two BBs so I know for sure that the problem is on my Storm. Tried doing service books, the diagnostic test, I even called my carrier and all they did was resend my service books! For about 15 minutes after they did it I was able to send messages again but now, it's back to being "mute". Any idea folks? Please help!
