So I just got an ipad mini for my birthday. This is my first ipad, and it's the wifi only version. Now I currently use my iphone 5 for pretty much everything, but most things will be converting over to my ipad now. Question. Lets say I'm typing up a note, doing something in an app "offline", aka when I'm not on wifi. Does that sync up once I am connected to wifi? How does that work? Thanks!
