I'd like to change the email address that my windows phone is linked to. It's currently on a gmail account, but i'd like to move everything over to my @outlook.com account

Is this possible? I don't want to lose all my contacts which are stored in the cloud (I.E if I upgrade to a WP8 device, I can still keep my contacts)

This is the only Windows phone device I have, so I'm not too familiar with how microsoft works on this front.

Is this possible? I logged into windows live with my gmail account and went to "change the email address", but it said I shouldn't as my Windows phone is linked to it?

As far as the xbox goes, I don't really care lol
