my unlocked BOLD cant send pictures straight fro my phone to face book any more?

Hi there i have a blackberry bold on o2 network the bold is unlocked and during the first few months i had it althoug i had no service or data plan whatsoever i was able to send pictures i had takrn straight to face book but now if i try this message pops up
" you are currently on a service plan that does not support this application. please contact your service provider for aditional information or to upgrade yor current service plan"
Has this got anything to do with me upgrading the operating system software from the blackberry website?
