Question about Microsoft Lumia 950 XL

1) I also think that the 950 is meant here, I don't know the 560 :)
2) What should be synchronised?
Pictures and music files can be accessed directly from the phone, like from a USB drive. Mail should actually be synchronised directly with the mail server. What else?

Hello, since the question was asked under the LUMIA 950XL, I assume that this device is meant in the question, a "Lumina 560 xl" does not exist to my knowledge.
There is a "Windows Phone" application in the AppStore that works with a non-updated Lumia 950 XL. see http://allaboutwindowsphone.com/features...
