Why are iPhones so restricted?

Ip don't get me wrong it a great phone, an awesome phone, but it has so many restrictions.

-you can't Bluetooth with any device, not even idevises
-u can't download anything from safari… Anyways please give an answer based on facts, I mean you pay so much and you are stil restricted, why can't they have this option that if you turn it off it lets you download stuff from safari.

Bluetooth works fine for me.
if you want more options, jalbreak it

Apple designed iOS to be a smooth and simple operating system to appeal to everyone. It has the power to run complicated apps and it's simple enough for a six year old to use. If you want to do what ever you want with your iphone look into jailbreaking it

Because Apple thinks that is better for business somehow. Remember in the beginning when only schools had Apple computers? Meanwhile, Bill was kicking Apple's derriere with Windows/IBM format in the business world.

There's constant frustration over their closed, restricted system, which is why competitively they miss out on a lot.
