Anyway, we all have our love/hate relationship with these things and for for me in the most part I love them, but it appears that some clever people (or not so clever people) at Apple had a plan, a plan which isn’t really widely known (not even in Apple) and isn’t advertised clearly anywhere.
Apple in their wisdom have set a restriction on the number of accounts that can be created from a single iOS device – this restriction is 3, yep 3 accounts.
So once you’ve created those 3 accounts (you can still log in with any existing account) you are stuffed if you need to create a 4th!
Apple’s advice (from their technical department including senior engineers) is either create a new account on another iOS device (therefore moving the issue one device across!) or buy a new device (really Apple!!).
Picture this scenario
Person A buys the latest iPhone, creates a new account, 1 year later they want the latest iPhone so off to eBay it goes.
Person B buys said 1 year old iPhone and creates an account, so far so good. They also then decide to buy a new device, back to eBay.
Person C buys iPhone, creates account – great, 3 happy people. They are a fool and drop the iPhone cracking the screen, but rather than repair they sell on eBay.
Person D buys broken iPhone to repair and sell on…..Person D or E will not be able to create an account so lets hope they already have an account!
So for the new buyer not so much a problem, but when the devices start changing hands its going to be a problem and from all accounts this was introduced in iOS 5 and considering we are on iOS 10 now I can see this becoming more of an issue.
How did this come about for me? Simple, re-provisioning iPads for other users and we hit the 3 account limit on a device that was 2 years old but stil perfect for what it’s intended use was meant to be.
