Coming over from Android, all these Apple features are foreign to me, especially this iCloud/Drive aspect. I'll start with my Contacts. All my Contacts are through Gmail. I went to [iCloud Contacts](https://www.icloud.com/#contacts) & I see like 12 contacts there, I'm assuming these are the contacts I added through my iPhone and they where saved to the iCloud? How do I add all my Gmail contacts over to iCloud/iPhone so I don't have keep Gmail on my iPhone and have Contacts button switched on. I don't want 2 places where my contacts are stored. http://i.imgur.com/zTKi2rw.png I see all these buttons turned on, what is all being saved to iCloud? Example; HBO GO says 6.3KB. I have no clue what this means. http://i.imgur.com/ZMrHTf9.png I don't have Ski Safari even installed on my iPhone anymore, what is this data stuff about? Same with Scanner Mini, I don't have the app installed. I'm just really confused about iCloud/Drive. I'm jailbreaking my phone tomight, so why would I need to backup HBO GO, Alien Blue or even Plex to iCloud? It's not actually backing the app itself, right?
