I need an app specifically to track the iPhone down. We have several in our family and I would need one that could be used to pinpoint where the phone is. In case of theft, or if I need to track the kids when they're walking home for whatever reason. Anyone got any advice on which would be better? I figured MobileMe was the way to go since Apple made it, but then I'm reading stories on how Cylay is just plain better for this purpose. Which would be best for me you guys? Thanks!
