Here's another tip. This affects most if not ALL scrolling. If you ever want to go back to the top just tap the time on the top bar. It'll zip you back to the top.
Another tip: sound settings.
When turning off mail sounds it'll also turn off you text sounds. This is for people who want to turn off text sounds. Keep in mind it also turns off the mail sounds. I haven't tested though if you'd get a sound when you get the initial popup on a received text, but when you send or receive will in the app you get no sound at all.
