Nokia Lumia 710 - How can I get Bluetooth Share application on my Nokia Lumia phone?

You will find this application in Store (formely Marketplace) under ‘Nokia collection’ from February, 2013 onwards. It is only compatible with Nokia Lumia 800, Lumia 900, Lumia 710, Lumia 610, Lumia 510 and Lumia 505 running on Windows Phone 7.8. To update your phone you need to have the Zune PC software or Windows Phone App (Mac OS) installed on your computer.
