I updated to 2.2 this morning. I had to go through and reset my specific notification tones for email, corporate email, messaging, talk, etc. I also had to update my ringtones for specific contacts. But as I received emails from my exchange account, the notification ringtone is not what I set it to. It is changing itself to "Default Ringtone" and that ringtone is not the actual default ring that I have set for my calls. It is a ringtone I set for a specific contact. I have turned the phone off and on again, but the notification tone for the email keeps changing itself back. I have also turned it off and taken the battery out for a minute, put it back in and turned it back on, and received the same results. It's not a huge deal, I am just puzzled as to why just that particular notification ringtone will not work correctly and where it is pulling this "Default Ringtone" from. Is anyone else having this problem?
