I'm having to change the email address associated with my Microsoft account, as I'm no longer going to be using the one that's currently assigned to it. I know this is pretty simple to do on my Xbox, but I also have a Windows 8 phone (HTC 8X). I know the only way to change the Microsoft account on the phone is to restore it to factory settings and start again - is this going to be the same for me changing my email address? Or will it just ask me to sign back in or something? Also, if I do have to restore my phone, is there a quick way of re-downloading all of the music I've downloaded through the Xbox Music store? And what would happen to the stuff I have backed up on Skydrive, would that still be accessible?
Sorry for all the questions, I just have about 10GB of stuff on my phone that I would be devastated to lose!
