You could try letting the user type what they want, then retrieving
the text and parsing the unwanted values out, then redisplaying it.
This would be kind of confusing for the user, though, since they'd
be happily tapping away, only to find that 50% of what they tapped
out would actually appear.
You could also just slap together your own keypad inside your app
using repeating buttons or something (I do this all the time, since
the Palm keypad's buttons are too small for some of my users to read
when they're doing inventory stuff in odd warehouse/lot like places).
It doesn't really cost TOO much in overhead...but you have to keep
that in mind too.
