I had my BB Pearl stolen recently and had to purchase a new one on Craigslist. I got a new SIM card issued by T-Mobile and everything worked fine. I have only recently tried to use the BB Messenger application and noticed that it is not listed on my drop down menu. When I go into Advanced options and scroll through the list of applications it lists BB Messenger as being one of them. I have also noticed that on my general message menu, there is no option for sending PIN messages. I have tried removing and re-installing the Messenger application, but it still doesn't work. Can anyone help?
