Few little tips/tricks I found out about...
when messaging (in Manilla sms or Pocket Outlook), you can double space, and it automatically adds a period after the last word and capitalizes the first letter of the next word (doesn't capitalize in Manilla sms).
2nd thing, in the new Manilla menu setup (you know, the menu that pops up with the soft keys), you don't have to always use the up/down arrows to scroll. You can just swipe scroll the menu. Came in handy with Google maps, with 3 screens of menu buttons!
Also, when in a call, you can hold the power button for 2-3 seconds and it will toggle speakerphone on/off.
FYI, I read in another post, the proximity sensor that turns the screen on/off when in a call is located just above the start menu on the phone (you can't see it). When in a call, put your finger just over that area, and the screen goes off. Cool, huh!
