this wont work for bbm. try a batt pull first but more than likely you didnt realize that the box for bbm was left unchecked during upgrade and it wasnt installed. only way to get it is reintallation of the os.
This happened to me when I upgraded the OS and I did a soft reset which just taking the battery out while the phone is still on and then replacing it and the phone will reboot on its own then any application that was missing should appear now.... Hope it works out..
