  • May I delete everything on my iphone 4s once everything had been transfer to icloud? I have been a iphone user for almost three years and I'm going to trade in my 4s to get the iphone 5.

  • If i sync my iPhone to my computer will it take my photos off my phone and put them on the computer? I need to have my phone synced for the app zedge but i don't want my photos to be taken off my phone. There's this bar and on it it says photos, app, ect. And next to it is a little button that says sync. So IIm guessing it will take my photos. But i don't want that to happen but i need to sync my phone. Is there anyway i can do it without having my pictures going on to the computer?
  • If I sync JUST music to iPhone on a new computer - do I lose everything? Hi, my computer is broken and in for repair but I want new music on my iPhone. If I plug my iPhone into my laptop (after unticking 'allow devices to auto-sync') and ONLY sync music… Will I lose everything on my phone or will my music just change? It suggests in a warning I can only sync to one computer and I'd lose everything - but I don't know if this 'everything' is actually everything - like my pictures - or just all my current music - which would be fine.
