My blackberry tour 9630 had an unexpected erroe yesterday. It suddenly restart itself. After it restarted, I wanted to use the bbm, but when I open it, all my contacts are gone! I had to insert my username again ( that means I have to start over). I did start over, and then I realize I lost my backup file, and when I check my friends phone, my 'old' bbm(with the same pin) is still there! Is there anyway to get my 'old' bbm back? All my contacts and messages are gone too! Thanks!
