SmileDial 1.1
(Release 1002): released 2009-02-02; requires iPhone 2.2 or later
Added a Settings option to Display Person's Name: if on, the person's name appears at the bottom of their photo. It is on by default.
Added a Settings option to Convert Numbers: if on, a number like "1 (800) MY-APPLE" will be converted to the numeric equivalent, "1 (800) 692-7753". This is off by default.
If a number from a Contact contains letters (e.g. "1 (800) MY-APPLE"), and isn't converted via the above setting, it is not auto-formatted, to avoid stripping off the letters.
Scrolling between multiple people (in the Pro edition) is now faster.
Flipping to and from the Edit Person view is now faster.
