Palm Pre to get third-party developed virtual keyboard?This article contains unofficial information.
Actually, the Pre already does come equipped with a keyboard on screen that changes orientation and is available in all applications and all fields. Currently, the only thing that this keyboard can be used for is to click on symbols or characters that are not included with the physical, sliding keypad. The developers goal is to attatch letters and numbers to the pop-up display that currently is on the phone, and viola! You would then have a full, virtual QWERTY keyboard that would work in landscape mode and in portrait mode without opening the slider.
Progress is being made, but the developers state that the current software should be characterized as pre-alpha and extreme caution taken if you decide to download it on to your Pre. For more information, check out the source link.
