This is a silly argument to make. By pretty much any standard, the iPhone has really good security.
Given how many high profile politicians, journalists and businessmen have gotten their phones hacked, the iPhone is not unhackable.
I for one am not comfortable with anyone having that much power over something that is supposed to be mine, so they are the same to me. Untrustable black boxes.
The greatest middle finger to Apple is freeing their hardware. Been at it since I built and booted a uCLinux kernel on my first iPod I got as a kid.
