In order to install the application on your Nokia 5800, I suggest you to set the date on your mobile device to one or two year prior to the current date. After the installation process is completed, you can set back your device date. Also, you can go to Menu > Tools > Settings > Application > App Manager. Here, change the Software installation to All and the Online Certificate Check to Off.
To connect to the device using Bluetooth, a pair operation needs to be completed. Put one device in listening mode and enable the Bluetooth. From the other device, activate Bluetooth and search for compatible Bluetooth devices. Once found, tap on it and pair it. If everything is successful you will receive a pairing confirmation. Once the device have been paired, you can use them for your purpose.
