Hi all...

I'm using a 3g iPhone, OS 4.2.1, successfully on T-Mobile. My only issue is that if someone leaves a voicemail, I get no indication of it. I get a missed call indication, but nothing to tell me that there's a new voice mail (the red dot on the voicemail icon). The voicemails are there if I go to check. Just wondering how to get the notification to work. Thanks.
