What you are asking for is something like T9 text input for addresses, text, etc. for the dialer. Unfortunately the dialer is numeric only plus some controls (pause, wait, delay, etc). Even 555-EATS gets sent as 5553287. Has what you are asking for ever worked on any phone that you have? What model? I would think that what gets interpreted as an alpha is more of a function of the receiving end and not the phone. Appears that the receiving end expects text input and unfortunately the dialer is numeric only. Might be nice to have a toggle for the dialer that changes it back and forth between dialer and keyboard, but I don't know of one.
