Can you "lock out" or disable the ability just to hit the gmail button and see the inbox. I am asking in order to avoid people from picking up my phone and being able to see my mail. Prying eyes and all that. I know I can lock the phone if I set it down but I would like to be able to sign into Gmail WHEN I WANT to. any ideas...LOve it so far by the way. Just got it today and everyone at work is oooing and ahhing over it.
