Your kids want that new phone with the camera, Web browser and 12,000 ringtones. You want some measure of control over who they're talking to--and you'd rather not dip into their college savings to buy it. One good compromise: the new Firefly (fireflymobile.com), designed for kids 8 to 12. It lets parents program up to 20 numbers that kids can call and receive calls from, so strangers are out of luck. The phone has just five keys, including two for Mom and Dad. So far, availability is limited to Ohio ((cincinnatibell.com) and the southeastern United States ($199 for 1,200 minutes; (suncom.com), but it will soon debut nationwide. One downside: no text messaging. They'll just have to pass notes.
