iphone security

Systems like Symbian have mobile security built in from the ground up; for example, the system asks before any new application can access phone data or the network (similar to capabilities-based UNIX security). Every program could do everything. I have programmed an installation program that opened a GPRS connection, downloaded a SIS file and installed it on the Symbian phone without user interaction!!!
This was a bit tricky but it worked fine on Nokia Series 60 phones an on Sony Ericsson P800 and P900. Evidently, an OS X-based phone lacks these safeguard. I guess that's the real reason Apple has been refusing to permit third party phone apps on the iPhone, even though they don't cause problems on other phones: the iPhone software architecture just doesn't seem designed for it.
