How's this for a parent hack? Ryan Neudorf's one year-old son always wanted to play with Ryan's iPhone, but he didn't want him to accidentally call Japan. So he built an iPhone app, iPlayPhone, to simulate the fun while keeping the phone's calling features safely tucked away.
From Ryan's blog:
I built it for my 1yr old son who’s always running off with my phone. It’s simplictic but super fun. All the buttons play goofy sounds. The onShake sound totally baffles my son, he’s like “woah, i shake it and is makes sounds…weird.”
Ryan sent me three free download codes for iPlayPhone (at the US iTunes store) — if you'd like one, leave a comment some time today (Saturday). I'll randomly choose three folks and post the "winners" tomorrow!
