I've been having this issue with my bold 9900, where sometimes when I recieve a text, email, or facebook alert I'll hit the "call end" button or the top "lock screen" button to shut off the ringtone but it won't stop ringing. I've notice this happens almost 100% of the time if I'm texting or on bbm.. anyone else experiecing this problem with not being able to shut off a ringtone alert?
