Wondered what people's thoughts were on the mail apps that come with the phone? I've been using the HTC app, but have noticed that after a day or so the notification sound stops playing when I receive an email. This happened for anyone else? Anyone tried both apps for any length of time and have strong opinions over which app is better? I saw a review that said the HTC app is better but the Google one doesn't seem too bad to me... Anyone using the Google app that would care to chime in?
