couple of questions about iCloud backup
Greetings. I backed up my iPhone 5 to iCloud a couple of times but didn't really understand it and mainly use iTunes. I was looking at 'manage storage' on my iPhone and see 2 iPhones and 1 of them says 'this iPhone' under it. Is the other one my old iPhone 4? How could i be sure before deleting it?
Also under documents and data i see some apps that i no longer use and when i click on a specific app, then edit i get the option to delete all. does this mean delete all of this specifc apps data, or all apps?
Finally, last time i did this icloud backup i lost a few of my recently added contacts. How can i backup to icloud again without this happening?
Thanks for any help.
