By that argument, I could say that because there is crime out there in the real world, everyone should be forced to live under martial law, have implants put in their heads to inform the government where they are and what they are doing at all times (for society's good and to avoid crime) and basically take away every single freedom you have for the sake of law and order.
This is going to extreme and is not even a valid argument. It's like saying freedom means I don't have to pay my taxes. Think again.
Now maybe YOU would like to live in a world like that and gaging by your statements about CONTROL over iPhone to avoid all this rabid viruses and trojan attacks going on out there (odd how I've used Windows since 1999 and have NEVER EVER gotten a SINGLE virus or trojan on my computer and I do NOT have a virus checker running 24/7. I check it once in awhile and there's never anything there. I use the heck out of the Internet. I must be lucky, eh? One in a billion with all that evil trojan/hacking/virus malicious crap going on out there. Or maybe if you have a bit of intelligence and don't download crap, you aren't very likely to get infected. The same applies to certain risky social behaviors with certain real world viruses.
This is just one person's experience, namely you. There are people out there who have had different experiences. I myself and have known people and people I know have known people whose computers had been infected with viruses and malware and so forth. When computer are so vulnerable, cell phones can only be more so because they are 1. away connected and 2. everybody needs a cellphone.
You can't always blame people who got infected with computer viruses for being careless or stupid. Instead of blaming the victims, the right thing to do is to make the computing environment more secured.
Personally, I like freedom. I like freedom of speech. I like freedom of choice. I don't like someone like Apple or Microsoft dictating what I can and cannot do with a computer I buy from them. And yes, the iPhone and iPod Touch are COMPUTERS whether you want to believe it or not. The world seems to be slowly turning into a giant fascist state. Some appear to not mind that one bit, I guess.
I hope you never buy a car because we would never know what would you do in our network of traffic.
