Yes, 15 seconds is plenty with good reception, I "normally" get a fix within about 5 seconds (or as little as 3). But since my code does have a 15 second timeout (where it then reverts to the cell tower location), and I've found that, sometimes, I still get cell-towers (maybe when the phone is in my pocket or whatnot), clearly 15 seconds isn't quite enough.

I will probably be adding a third mode that is "Always use GPS", which has the same logic and timeouts, but simply will *never* use a cell location, simply not posting any update at all if it didn't get a "gps quality" fix within the timeout. Then you, as a user, have the choice suitable for your environment, i..e

- very urban (New York city-canyons and offices): Cell only
- medium (smaller city with some open spaces): Cell+GPS
- rural (nearly always good gps fixes): GPS only

Should be a trivial change.
