FYI, Blackberry BIS seems to be having some problems right now. The issues started late last night and has continued on to this morning. Carriers are said to be working on the fixes for the issue so consumers are encouraged to be patient while they work the kinks out.
Are you having problems with your Blackberry?
**UPDATE: As I was posting this my phone Data services lit up, if yours haven't you might need to manually reset your provisioning. I recommend you do a quick battery pull, once your phone comes back online, if its still not receiving data go to Menu, Options, Mobile Network, Click Menu and Select Start Provisioning. You should be fine from there, comment below if you have any further issues.
