Firefly Mobile, the carrier responsible for its namesake kids' phone, has submitted a new design for approval by the FCC. Whereas its predecessor limited kids to calling parents or for help, the W100 has a proper keypad, in the form of a touch-sensitive area that changes based on the task: numbers appear for dialing, while selecting a game will bring up directional arrows. The W100 also adds music and video playback, along with a camera, bringing it closer to par with its adult counterparts. No more details have been formally announced. [via Engadget]
