Not sure what carrier TIM is but if it's really one of the big ones they may have discovered your BB and If you do not have a Blackberry data plan you now find it blocked for data use. so the question I would ask is " do you have one"
Before you go wiping the BB try aiharkness idea first. Pull the battery while powered.
