|I'm really quite sure that your device needs to be jailbroken to install any software that Apple doesn't approve. I am talking of deliberate targeted spying of a particular person / iDevice such as the type you have pointed out. |
I have done a little more digging and still cannot come up with anything that operates in the Apple ecosystem without their approval (without a jailbreak being applied) so I decided to look directly at the software vendors site(s) to examine their compatibility requirements. They freely offer this information because they need informed subscribers to pay them for their service.
*** All iPhones, iPads and iPods MUST be jailbroken prior to installing Mobile Spy. You cannot download or install Mobile Spy if the iPhone is not jailbroken. ***
Towards the bottom of the page:
Your iPhone, iPad or iPod MUST be jailbroken prior to installing Mobile Spy. You cannot download or install Mobile Spy if the iPhone is not jailbroken. We DO NOT PROVIDE SUPPORT for the jailbreaking process. This must be done by the customer. You can search online for numerous sites with tutorials that can assist you with this process, such as iClarified or Redmond Pie.
Further down the page under compatibility they simply state:
And right beneath that
iOS 8 coming soon!
They state iOS 8 coming soon because the jailbreak for iOS 8.x.x and iOS 8.1 is very very recent. So recent in fact that it was released before Cydia was made compatible meaning it is useless for most end user jailbreakers.
On their install guide page:
1. Jailbreak the target iPhone. It is very important that the target iPhone is jailbroken in order to install SpyBubble...
And they go on to stipulate the importance of jailbreaking the device to install and run their software.
This confirms for me that software of this nature needs an Apple device that has been jailbroken to function. Apple would never allow this kind of software, they would risk losing a massive customer base if they did. If you have proof that it can be done without the device being jailbroken I would urge you to provide Apple with it. They will very quickly close any exploit that allows 3rd party spyware to be installed on an un-jailbroken iDevice.
If we were talking about a Windows or Android phone then the possibility of this happening is much greater.
