I'm guessing you are trying to dismiss the notification using the steps outlined in the second post
here?
The second post
here has a shortcut to get nearly all the way to the menu described above...
I don't know if
this link will work, but I did a search at
pdaphonehome.com's 6700 forums and found numerous threads. You may want to try searching there...
OR, you could just try (and buy!)
Pocketmax's PhoneAlarm. It allows you to manage all sorts of ppc phone settings, including ringers, profiles, notifications, and much more...I've been using it ever since I got my i730. It's probably the one program I couldn't do without.
Hope some of that helps~
