I try to keep my data access to a minimum, so I switch it off when not in use. But I started noticing something rather annoying... When I get a call and it goes to voicemail, my phone's LED will flash green but I won't get any audible notification. If I turn on data, I'll suddenly get notification sounds and the voicemail will be downloaded to the phone for off-line listening (I don't have to dial into vmail). I can't seem to find any information about how this is controlled... Certainly there should be a way to be notified of a voicemail message without being data connected?? I checked the manual and there wasn't any reference to needing a data connection to be notified of a voicemail message. In the settings, I have specified a notification sound for voicemails.
