Google Latitude is pretty awesome as a native app for other phones but it sucks on the iPhone because it's only web-based. As far as I know, you have to refresh Safari manually to update your location, and I believe this means you have to open Safari and refresh it even with multitasking support. Anyone know of any apps that run in the background and update your location using GPS? I've seen the navi ones but those don't allow anyone else to see where you are in real-time. I'm looking for something where anyone can go online and track my location without me having to update it manually. Any ideas or thoughts on this?
