[CLOSED-85][Android] Doubletap on YEAR on Picker widget opens the phone application
I was testing the examples on my Motorola Milestone with Android 2.1 and when I opened the DatePicker widget and tapped 2 times in the Year field, my Dialer application opens with '1980' on the numberfield to call.
I didn't have a chance to test in another phone, but this is a little wierd. I didn't find this behavior in any other widget.
