I had this same issue. Anyone with the Voicemail ICON that wont clear, needs to try one of these 2 things.
Call TMO. Apparently they are doing something with the networks and its affecting a lot of us. Its a known issue and they can help you reset the voicemail. No need to change settings, reflash or etc... I did this and it was just a waste of time.
Another thing to try if you just hate calling the reps, is to leave yourself a VM from another phone and press and hold 1 to enter your TMO VM. Once in the VM, see if the message comes up. If it does, delete the message and it should clear the annoying notification.
I couldn't get my VM to work since I was using GVOICE, so I had to call in for them to reset everything. Should be a quick reset on their end.
