Tools Installation files may be transferred to your device from a compatible computer, downloaded during browsing, or sent to you in a multimedia message, as an e-mail attachment, or using Bluetooth connectivity or infrared. You can use Nokia Application Installer in Nokia PC Suite to install an application to your device. If you use Microsoft Windows Explorer to transfer a file, save the file to a memory card (local disk). After you install applications to a compatible memory card, installation files (.sis) remain in the device memory. The files may use large amounts of memory and prevent you from storing other files. To maintain sufficient memory, use Nokia PC Suite to back up installation files to a compatible PC, then use the file manager to remove the installation files from the device memory. If the .sis file is a message attachment, delete the message from the Messaging inbox. Install applications and software indicates a .sis application, a Java application, that the application is not fully installed, and that the application is installed on a compatible memory card. Important: Only install and use applications and other software from trusted sources, such as applications that are Symbian Signed or have passed the Java VerifiedTM testing. Before installation, note the following: • To view the application type, version number, and the supplier or manufacturer of the application, select Options > View details. • To display the security certificate details of the application, select Options > View certificate. See 'Certificate management', p. 110. • If you install a file that contains an update or repair to an existing application, you can only restore the original application if you have the original installation file or a full back-up copy of the removed software package. To restore the original application, remove the application, and install the application again from the original installation file or the back-up copy. • The .jar file is required for installing Java applications. If it is missing, the device may ask you to download it. If there is no access point defined for the application, you are asked to select one. When you are downloading the .jar file, you may need to enter a user name and password to access the server. You obtain these from the supplier or manufacturer of the application. 1 To locate an installation file, press , and select Tools > App. mgr.. Alternatively, search the device memory or a memory card (if inserted) in File mgr., or open a message in Messag. > Inbox that contains an installation file. 115
