EGPS works with my i780. Using My Location in Google Maps, it was able to tell me my approximate location, based on the nearest cell site. You can't use this to navigate, though and it requires an active GPRS/3G connection for data access.

Not as practical as when using the built-in GPS receiver, EGPS has very poor accuracy (approx. 500 - 1,000 meters) and the My Location dot in Google Maps only indicates the cell site you're currently associated to. But this just proves that cell sites do provide their coordinates when queried by the phone.

I turn this on only if satellite acquisition is taking too long... which is seldom.
