youmail is a visual vm app and its free!! you can even assign different GREETINGS to each contact to hear when they call lol.
I love youmail it is awesome and free. Try it
I agree.
What's really cool about YouMail is that when someone calls to your cell phone, the outgoing message addresses them by first name... "Hi John, Peter can't talk your call right now...."
My friends are constantly blown away by that.
Also, your phone DOES let you know that you missed a call, so I don't understand how someone can miss a call from YouMail, and not get it for hours.
At worst, you'll see in the notification bar that you missed a call, you tap on YouMail, and if it hasn't downloaded a message from that person, you can maually have YouMail check the server and download any new messages.
