There was also a program that can map your friends iPhone location to your google maps and you can get their location (of course they have to agree to this).
Loopt I believe. They make it for the Android based HTC G1 and Blackberry also. I'm optimistic about the Android platform. I also really like the Iphone, but Apples strict control on its products irks me. The G1 has a nice touch screen and what looked to be a decent browser, but it doesn't come off as nice because the screen is smaller than the Iphones. But if you like those mini-keyboards you might find it usefull; just probably not for medical software.
