Same apple id with different device?

Does same apple id means what you have downloaded on the other device will automatically re-downloaded on the other device. For example. On my iphone 4 i downloaded instagram, and when i check the app store using my iphone 5 there's a logo saying re downloading. ( cloud like with down arrow). Hope someone can answer me.

Yes. If you have 2 apple devices linked to the same apple id they will all download the same apps.

Yes but you have turn on this feature from Settings to Download Automatically or Manually tap the cloud with arrow button to redownload.

  • Will my jailbreak on one device transfer to another device via iTunes? So I bought an iPhone 5 today and I'm afraid to sync it to my Apple ID/ iTunes because my 8GB iPod is also synced to that iTunes account and its jailbroken. I don't want my jailbroken iPod to affect my iPhone 5. Will it affect it? I don't think it will but I just want to make sure before I sync it for the first time.
  • What can I access on a different IPhone that uses the same Apple ID? So my mum is using my old iPhone 5, and I got a new iPhone. My old iPhone is still using my Apple ID, as well as connected to iCloud, and has photo stream, and uses iTunes on my laptop. I was wondering if I would access to any contacts, messages, photos or anything on that old iPhone without actually going on the iPhone? Because I don't know the passcode. Or if there's anyway to get into the phone?
  • Two different computers, two different iTunes.can I use the same Apple ID? I have iTunes on my computer that I use for my iPhone, and my mon just got an iPod Touch and wants me to fill it for her. I'm going to use her computer to do this, which currently does not have iTunes. Once I download iTunes, can I use my own Apple ID to download songs and apps onto her iPod? Is it possible to do that without disturbing what's on my phone, or do I have to make a whole new iTunes account for her?
  • How do you stop calls coming from one device coming to your device from iCloud (apple iPhone)?
