An iPhone Spy App is basically an application that allows you to spy on somebody else’s iPhone.
The two main examples of an iPhone Spy App are Flexispy and Mobile Spy. These two applications have slightly different features, but are extremely powerful programs that allow you to keep track of the iPhone and its user.
For example, it is possible to track the iPhone using its built-in GPS (iPhone 3G and 3GS only – the earlier model did not have a GPS receiver), as well as read all SMS messages sent to and from the iPhone. The calls record can be read, with the calls linked to the user’s contact list.
Of course, different people have different needs – and different budgets. While Mobile Spy has a simple pricing model (there is only one version of the software), Flexispy has several different versions, starting with a basic version, right up to the very powerful Pro-X version.
