    Re: GPS and service providers

    I am pretty sure a provider cannot block your GPS if your using it in your own app... It's a closed system afaik, I can use GPS without internet capability for example... BUT I guess they could block the A-GPS part, which would make getting a gps fix a slower process...

    Re: GPS and service providers

    Hi,
    I too have the assumption that GPS cannot be blocked by the operator,But if there are no satellites available,then its not possible to get the information.

    Thanks

    Re: GPS and service providers

    well with the first generation iphone the cellid is naturally available (its a phone after all) and this information in combination with a database of cell-id/lat-long pair can give a very rough position depending on how many cell's and base-stations are in your area... thats why you see a big circle in which you "could" be, and not a specific place (like GPS would do)...

    Re: GPS and service providers

    If you buy a handset from an operator, it may be a device that has operator-specific firmware. While the operator cannot "block" GPS, they can sell you a device which has specific functionality removed or restricted. Some US operators have sold devices that have had their GPS functionality restricted (certainly in Windows Mobile devices, I'm not sure about Nokias). However, that restriction has been factory-built into the handset. If you buy a "generic" device direct from the manufacturer, and then use it on one of the offending networks, GPS will work fine - you cannot "acquire" the restriction.
