(The ephemeris, which doesn't change very often, and requires a clear signal from at least 3 satellites so it can often take a while with a standard GPS receiver.) Then, it gets the rest of the information from the satellites as any GPS receiver would.

    I'm still not sure whether the GPS can work as a standalone receiver, which would mean without using the assistance, but to say that it always calculates the position from cellphone towers is false.

    Anyway, WHERE's update means it finally finds my position now.
    That might explain the problem. I noticed in the Sprint store, the 2 demo Pre's couldn't be found with location services. But the two demo phones were deep within the store and the store had very few windows far away. So maybe the OP was attempting to locate himself deep within a building. Perhaps trying to locate outside with satellite line-of-sight will yield better results.
