hi everybody .. i just bought BB 8900. and i have no experience about GPS.. so my Q is i can use the GPS everywhere, or just limited for some countries ...

and my second Q is i can use the GPS without SIM card since the GPS served by satellite signals i mean this service doesn't related to the operator .

thank you for advance

gps should be able to be used everywhere. as you stated its based on satilite use. and unless you are in a underground cavern it doesnt matter what country you are in. however. it is most likely that the mapping programs wont work. but i am not sure about that. since it downloads on the go and is not dvd based i suppose mapping software should work

as for the second question gps will work without sim card, so that wont be a problem

GPS will work without a SIM. However, the map application will not as you need a BB data plan for that. Also, the device needs to download a current ephemeris table every so often so it knows which satellites to look for and where they are. GPS is in an elliptical orbit, not geo, so the locations change.

With GPS you get a latitude and longitude readout. If that works for you, then you are good to go. If not then you need a map which requires data (and a SIM card on a GSM device)

To connect to GPS, especially for the first time, you will need the ephemeris table download and be outside with a clear view of the sky. it can take up to 20 minutes to lock on and find you. It also helps if you locate yourself on a map as close as possible (not necessary, but speeds things up).

For more info, look in the GPS & Maps section.

Funny thing happened when I turned on my 8900 and loaded up google maps for the first time. I was inside my house and it found me. I have the blinds closed. I have no idea how it knew. Since then I've really enjoyed having it.

Actually sometimes GPS is able to acquire satellites even when indoors.

You can run but you can't hide ...

Google Maps uses cell tower triangulation to locate you initially while GPS is established. You should have seen a small box and large circle around your position saying your location with 1700 meters or something to that effect. Once GPS is locked on, it will show like 10 meters or so.

GPS uses radio signals so reception inside is possible. However for the initial lock you need to be outside. Works better that way.
