What do kids love to do the most? Oh yeah, get lost and give their parents a heart attack. I know I did, and I'm sure a lot of you Gizmodoians loved to do it as little tikes. mTrack is releasing what it calls the UK's most accurate child location device. KidsOK uses GPS to allow parents to locate a kid within 20 meters. The system does have some excellent features that other child safety phones don t, such as the ability to have parents text messaged when the child leaves a set area. This phone is available in a rainbow of colors and is available for $88 over in the U.K. No word on how much the monthly fees will be.
