The app doesn't really need the functionality of 1.6 anyway (for now),
it just makes the Text-to-Speech piece a lot cleaner, but until most
people have Donut I'll stick with Cupcake compatibility.
FYI, RC3 uploaded tonight:
http://android-smspopup.googlecode.com/files/SMSPopup-1.0.0-rc3.apk
Fixed up text entry on the quick reply so it uses auto-caps and auto-
correct, plus cleaned up the translation files and made some other
minor tweaks.
