Frankly, the line between hacking the system via security vulnerabilities for 'good' vs doing it for 'evil' is a razor thin-line.
I'm rooting for the cat.
IMHO.
Here's an article that states otherwise:
"Why I Won't Buy an iPhone"
money quote:
Why all the sturm und drang? Apple Chief Executive Steve Jobs will tell you opening the device could leave the network vulnerable. Carriers such as AT&T (T), Apple's U.S. iPhone provider, "don't want to see their West Coast network go down because some application messed up."
Hogwash, I say. Like many BlackBerry users, I've installed and removed scores of applications from my BlackBerry over the years, and never once heard a peep from T-Mobile (DT) about bringing down its network. No one has yet been able to explain to me how even the most ill-designed software could conceivably do such harm to the wireless network.
And really, is the iPhone so delicate that one nasty application damages its software permanently? I thought the device runs Mac OS X. If you believe Apple's marketing, the operating system is rock solid, hard to break, easy as pie to use, and so on. One bad application can do all that damage? The iPhone itself isn't just a phone or an iPod. It's really a mobile computer. Apparently one so powerful that software developers are forbidden to do anything for it, short of cute little Web-based applications, yet so sensitive that it's easy to screw up. That's one way to inspire confidence in a product.
