Sometime next Friday or Saturday, I'm going to be getting a Nokia Lumia 521. I was wondering if someone could point me to any Windows Phone 8 guides, as I'm a newb. to Windows Phone or any smartphone, in general. I already know how to upgrade it to the Windows Phone 8.1 Preview. Which I plan on doing. I'm also curious on if I can use a regular 64 gb. sd card with it or if it has to be a special sort of sd card ?
