A quote from Steve Jobs during the iPhone SDK Press Conference last week:
If they write a malicious application we [will] track them down and tell their parents.
In other words, the iPhone applications will need to be digitally signed by Apple, and the developers will be required to register with Apple. It will be interesting to see what kind of information developers will be required to provide to Apple to register. Will they ask for the developer’s credit card number? How will the developers authenticate their identity with Apple before they are allowed to submit their applications to be included in the store inventory?
Jobs also displayed the following slide to illustrate what types of applications will not be allowed on the iPhone:
- Apple may have a difficult time auditing applications to ensure they meet their criteria. What is the absolute definition of malicious in the given context? Malicious to whom? The end user, Apple, or AT&T? Perhaps all of the above. Now, how does Apple go about obtaining assurance whether a given application is malicious or not? Will someone try out every application that is submitted? Will someone at Apple review the source code of every application to ensure it does not invoke any malicious operations and only calls published APIs?
- Applications may not run in the background. This is quite likely to be a decision based upon processing resource constraints. Note that Apple’s own iPhone applications such as Mail, iPod, and SMS do run in the background.
- The Unforeseen clause means that Apple reserves the right to ban any application at any time. Will they be reasonable with the developers? I don’t see why they wouldn’t be as long as it doesn’t hurt their bottom line, for example:
11:32AM - We asked: Will SIM unlock software be considered software not allowed in the app store?
A: Steve: (pause) "… yes." Laughter.
