Ok, so this has happened to me twice today now... I go to chat with someone on BBM and then it takes me to a screen that says "Unable to Connect. you need a data plan to use BBM. Please contact your service provider for details" I have a data plan, I am able to send/receive emails, texts, etc. This has never happened prior to today. It seems to fix itself when I reset my phone, but that's not a solution in my opinion.
