Positioning; Positioning With Your Device - Nokia 5530 XpressMusic User Manual

The security icon does not indicate that the data transmission between the gateway
and the content server (where the data is stored) is secure. The service provider
secures the data transmission between the gateway and the content server.
Security certificates may be required for some services, such as banking services.
You are notified if the identity of the server is not authentic or if you do not have
the correct security certificate in your device. For more information, contact your
service provider.
Important: Even if the use of certificates makes the risks involved in remote
connections and software installation considerably smaller, they must be used
correctly in order to benefit from increased security. The existence of a certificate
does not offer any protection by itself; the certificate manager must contain correct,
authentic, or trusted certificates for increased security to be available. Certificates
have a restricted lifetime. If "Expired certificate" or "Certificate not valid yet" is
shown, even if the certificate should be valid, check that the current date and time
in your device are correct.
Before changing any certificate settings, you must make sure that you really trust
the owner of the certificate and that the certificate really belongs to the listed
owner.

Positioning with your device

You can use applications such as GPS data to determine your location, or measure
distances and coordinates. These applications require a GPS connection.
Your device does not have an internal GPS antenna. To use applications that require
a GPS connection, use a compatible GPS receiver (accessory sold separately). Use
Bluetooth connectivity to connect to the GPS receiver.
You can also use network-based positioning with your device.
