The Openwave select element implementation presents one user-friendly list with numbers which act as accelerator shortcut keys, allowing the user to select an option by pressing the corresponding number on the keypad rather than scrolling to it. Keep soft key labels to 5 characters or less. Many devices cannot display soft key labels that exceed 5 characters, and will truncate or abbreviate any labels that are longer. Use Wizards instead of forms. By using a single card for each input of information, the user can follow a natural process of entering information.
User studies show that wizards make for a better user experience than forms.
Finally, avoid having a separate 'submit' card. The last 'ok' of the wizard should in fact be the 'submit' option. This avoids an unnecessary additional click. This may result in the loss of important information. Test your application on small-screen devices to make sure menu titles and input field prompts fit.
