Hey Where Are You?: A nifty li’l iPhone OS 3.0 location app featuring push notifications (free for a limited time)

Basically, this allows you to keep and send dibs on your location and those people you care about.

If Rosanna wants to know where I am, she can simply send a request which pops up on my iPhone like a text message. I can reply and she’ll get a similar little text message, and she’ll be able to view my location on a map.

Seems like a great way to keep in touch.
