T-Mobile Visual Voicemail is the only app for T-Mobile customers to enable visual voicemail. It gives you a friendlier way to access and manage your voicemail. One sentence summary This application gives you visual voicemail in a visually repulsive package. Harware I have T-Mobile G1 Pros - Does what it says: browse through voicemails - Gives you option to switch to loudspeaker - Practical 3 button layout to Delete, Turn on/off loudspeaker and call back - Swipe to switch between voicemails Cons - UI needs A LOT of work, very cheap looking (especially in landscape mode) - No option to delete all voicemails or to select many and delete - Does not work with bluetooth headsets, audio will still come out of phone - No screen lock when listening to voicemail, your ear will undoubtedly hit the on-screen buttons and mess things up - After I listen to voicemail, loudspeaker stops working Bottom Line It is definitely not the best visual voicemail app in the Android Market but it is the only one for T-Mobile users. I find it hard to believe that this app was developed by a big corporation. I would expect T-Mobile USA to develop an eye-catching, beautiful less-buggy app. And given that this app has been out for almost 2 years, I think it's time for my expectations to be met.
