Just got my Touch Pro

Hmm,
1. no it should not! I recommand you to go to nearest sprint store for consult with them. (If it is spring you have?)
2. You mean that when pressing the keyboard keys they make a high clicking sound? IF so, yes, they will wear down after a little usage, note that they too should not be TOO loud.

Hi there!

(I get to answer the easy one) - Just click the Home button on the the left upper corner of your button pad (with the little house on it next to the d-pad).
It will minimize the app you're in and take you to the home screen.

Long way to get there: Tap Start/Today.

To get back to your app: Tap the litte = sign with the small arrow under it in the very upper right hand corner (where your x & ok button normally show up). Your open windows will display, just tap on it - and voila!
