Samsung SGH-i780 has been on Navigadget before. Today we have a video from unwired about the A-GPS functionality on that device.

A-GPS improves the performance of GPS receivers by providing them with notes that they would ordinarily have to download from the GPS satellites. With A-GPS notes, GPS receivers can operate faster and more reliably. To produce use of the A-GPS functionality though the phone radio needs to be

turned on which means you can’t use it in flight mode.

A nice feature is that Samsung SGH-i780 will actually let you know whether the A-GPS receiver is in use or not.

The video shows how Google Maps makes use of the info obtained by the A-GPS receiver.
