The latest version, SpellDial 2.0, is available on the Android Market. This version supports Android 1.5 (Cupcake) through Android 2.1 (Eclair for Nexus One).
One feature has been removed: the type of the primary phone number. I'll look at adding that back in. Please send any suggestions or comments to email@example.com. Thank you!
