It's called Mobile Me.  Perhaps you have heard about it.

It's a free app available for these smart phones.  I think the original purpose was to locate your cell phone if it's lost or stolen.  But that's not what folks like me are using it for.  I have it on my son's phone and can locate him wherever he is.  I can zoom in and see the streets he takes or use the satelite mode and actually see the houses/businesses that he visits.  I feel a little creepy using it, but it does ease my mind if he's out with friends.  Robert thinks this is just a little too much.  What do you think?  Leave a comment to let me know if I'm meddling a little too much.
