Treo makes or answers calls when it's in a briefcase or pocket
Items in your briefcase or pocket may be pressing the onscreen Answer button or
otherwise activating screen items. If this happens, be sure to press Power/End
turn off the screen before placing your Treo in a briefcase or pocket. You may also
want to disable the screen's touch-sensitive feature during incoming calls (see "Using
Auto-Keyguard and touchscreen lockout" on page 155).
