Google announced API for LBS on Mobile
Google launched the Gears Geolocation API for mobile on last week on their official Goolge code blog, and Mobile Blog, with a screenshot of a sample mobile site, Rummble and video demo of lastminute.com of UK.
On mobile devices with Gears installed, Javascript functions grab the cell-ID of nearby cell towers or GPS (if either is available) to improve the postion fix.
The two methods:
getCurrentPosition() makes a single, one-off attempt to get a position fix.
watchPosition() watches the user’s position over time, and updates the position changes.
Also,
lastPosition get an approximate position fix
The bad news is that API is available on Internet Explorer, Firefox and IE Mobile (selected devices only – incl. Samsung Blackjack II, HTC Touch Dual, TyTN, Palm Treo750 etc.) and will be available on Android. I was going to try it with S60, until I read the line on the announcement.
The good news is that they are currently implementing the editor’s draft of the W3C Geolocation specification with Microsoft and Mozilla guys.

At the beginning, Google Geolocation API has determined the location for only Americans, for the other it has returned “unknown”. Later this service was advanced, but it often does not show results even for developed countries as yet. For such cases, there is a simple javascript extension to the Google API, which gives back the country of user.
