Nokia has officially made the Windows Phone 7.8 update for the Nokia Lumia 505, 510, 610, 710, 800, and 900 available for download. Remember that this update, apparently, is not Windows Phone 8 but will pretty much be like Windows Phone 8. These Lumias were announced back in 2012 and like what Nokia already promised will update these phones into 7.8. Anyway, for those who uses one of these devices, you need Zune software (for Windows) or the Windows Phone App (Mac). Enjoy the update!
