Most of us use our iPhones to make phone calls, play with apps, watch movies, and read books. If you have young children around, you could use the Ubooly pet to turn your iPhone into a toy for them. The toy uses your phone as its face. It learns and remembers things about your child. Ubooly talks to your child and plays games. The companion app for this is free. Interested? You can pick one up for $30.
