Great question! You actually have a Visual Voicemail function through T-Mobile.com. Log in using your T-Mobile ID and password, click the Phone tab at the top, then click the button that says Check Voicemail. Depending on how many voicemails you have, it may take a moment to load. The really cool thing about this feature is that you can save as .MP3 (or mutliple .MP3s as a .ZIP file if applicable) or send the selected voicemails to an e-mail address.
