We have been working on adding support for touch screen devices like the BlackBerry Storm. In the meantime, some users have sent us a little tip to share with other Storm users:

You can control the Wattpad menu and reading screens using the virtual keyboard. Press the MENU key and select “show keyboard” Use the TY, DF, JK, BN keys for up, down, left, right respectively and press Space to select and toggle auto-scrolling.

Thanks for the tip! We hope to have official support for BlackBerry Storm soon.
