I think a few people have tried to ask this before, but just in case...
On my old Smartphone, I was able to type in a name using the letters below the numbers on the phone pad. The phone would then search for matches. E.g. for Brown I would type 27696, being the numbers associated with the letters on the phone pad. As I typed, the phone directory would be searched, narrowing down as I typed in more letters/numbers.
Does anyone know of a patch, add-on or whatever that would enable this feature? Why, you may ask? Because I find it a pain to have to always slide out the physical keyboard in order to search for a name.
