@Pieter: Despite Matthew's commentary, you may find this article interesting. forbes.com/sites/andygreenberg/2012/02/14/… In essence, while we cannot prescreen for malware (something that isn't even possible to do in the general case, Matthew's illogical beliefs aside), our default repositories have a fairly good filter for "trustiness" (happily pulling things they find fishy on a moment's notice), and the very people who join our community are the very sort that frown upon this kind of data collection.

I am sorry, but Matthew is not "correct here". Apple cannot statically determine the set of system calls that a binary may choose to execute at runtime: it is trivial for a developer to simply inline assembly a 'svc 0x80' instruction, and there are numerous ways of hiding what the value of r12 would be at the time of the call. If you believe otherwise, I highly recommend reading introductory texts on operating system design. Given this, it is now entirely possible for any App Store app running on a firmware revision for which the jailbreak community provides an untether to rootkit your device.
