■ Software updates
Important: Use only services that you trust and that offer adequate security and 
protection against harmful software.
Nokia may produce software updates that may offer new features, enhanced functions, or 
improved performance. You may be able to request these updates through the Nokia 
Software Updater PC application. To update the device software, you need the Nokia 
Software Updater application and a compatible PC with Microsoft Windows 2000 or XP 
operating system, broadband internet access, and a compatible data cable to connect your 
device to the PC.
To get more information and to download the Nokia Software Updater application, visit 
www.nokia.com/softwareupdate or your local Nokia web site.
Downloading software updates may involve the transmission of large amounts of data 
through your service provider's network. Contact your service provider for information about 
data transmission charges.
Make sure that the device battery has enough power, or connect the charger before starting 
the update.
If software updates over the air are supported by your network, you may also be able to 
request updates through the device. See “Phone,” p. 35.
■ Phone software updates
Your service provider may send phone software updates over the air directly to 
your device. This option may not be available, depending on your phone.
Warning: If you install a software update, you cannot use the device, 
even to make emergency calls, until the installation is completed and the 
device is restarted. Be sure to back up data before accepting installation 
of an update.
