If you've got hundreds of contacts in your Nokia N8's phonebook, it's always a worry that you may lose your handset, and struggle to get in touch with your friends. There's no need to worry, however, as it's easy to back up your Nokia N8's phonebook wirelessly using Nokia's Ovi service. Join us after the break to find out how...

To sync your phonebook with Nokia's Ovi service, you'll need to set up an Ovi Account. You'll need this for the Ovi Store anyway, and to use Nokia's social networking widget, but once you've set up an account you're good to go with all the different features.

Head over to contacts.ovi.com once you've set up an account. From here, you'll be able to manage all your contact details – from adding new contacts, to editing existing ones, to deleting unwanted numbers.

It's easy to manage all your contacts once you've logged in, as everything is displayed in a big simple grid – complete with photographs if you've already added them.

To sync the numbers from your Nokia N8's phonebook to Ovi.com, the best way is to add a Sync shortcut to your home screen. Check out our Nokia N8 Ultimate User Guide to find out how to edit your home screen. You can also open the Sync app by clicking the Menu button, pressing Connectivity, Data Transfer and then pressing Synchronise.

Click Options and Sync Settings to adjust your username and password details. You can also adjust the settings to change what items are synced – make sure that Contacts is ticked before you start. You can set the Sync function to work automatically every month, or manually.

Once you've pressed Synchronise, head back to contacts.ovi.com, where you'll see all your newly synchronised data. You can synchronise more than one Nokia handset at a time – so it's also easy to keep multiple phonebooks up to date.
