Nokia has released a new desktop app that will make it even easier for iPhone, BlackBerry or Android users to ditch their current phone and move to a Nokia Lumia.

"With Welcome Home, you just plug in your Lumia to your computer (Mac or PC, your choice) and the application handles moving your contacts and personal data – quickly and easily," says Nokia.

The new piece of software will let iPhone, Android and BlackBerry phone users move their contacts, calendars, pictures, songs and videos from their old phone to Microsoft Live.

Nokia says the software will also scan your old apps and do its best to find them on Windows Phone, or if they aren't available suggest alternatives.

For those apps that it does find it will provide QR codes and links to let you download them.

The new app is available from today via Nokia's website.
