 Shooting images with my Nokia N900 will only fill in EXIF data for
 "DateTimeOriginal", not the tag "DateTimeDigitized" which Wordpress solely
 uses.

 Grabbing data from DateTime and/or DateTimeOriginal would increase the
 amounts of correct EXIF date data collected when uploading images.

 Attaching sample original image from my camera. CLI tool 'exif' when
 grep:ed with 'Date' outputs the following for the attached image:
 {{{
 Date and Time       |2010:06:25 15:47:14
 Date and Time (origi|2010:06:25 15:47:14
 }}}
 'exif --list-tags *jpg|grep Date' results in the following (* meaning data
 exists):
 {{{
   0x0132 Date and Time                   *      -      -      -      -
   0x9003 Date and Time (original)        -      -      *      -      -
   0x9004 Date and Time (digitized)       -      -      -      -      -
 }}}
 wp-admin/includes/image.php has the function which retrieves this
 metadata.
