You're specifying the enableHighAccuracy option, right? And if so, is it
giving you any greater accuracy than you get without it specified?

If specifying enableHighAccuracy isn't getting you accuracy greater than
15m-75m in some particular mobile UA, that sounds more like an implementation
deficiency that needs to be corrected in that UA -- not a spec deficiency.
