What are you basing your statement on? Verizon and AT&T phones have been pegged at different minor versions of iOS many times.
People want to believe Apple is some magic company that can do no wrong, but that ignores the extensive amount of QA (both in house and at the telcos) that happens before any release like this (as a longish time OS X user, I should know.)
When an iPhone update is released, the update becomes available worldwide for everyone. There is no delay waiting for individual carriers to approve the update, like there is with Android and Windows Phone.
That's because Apple owns the hardware. It's not really fair to compare the two shops in this way, considering the differences between an OS, and an OS + platform.
Nokia also owned the hardware but Symbian updates were carrier approved. Microsoft owns the hardware but Windows Phone updates are carrier approved. BlackBerry owns the hardware but Blackberry OS updates are carrier approved.
Not one single thing in your comment is factually correct. In fact, both points are demonstrably the opposite of the truth. Apple is not perfect. It is very good at marketing, very good at aesthetic design, decent to good at acquiring marginally above average hardware, and ranges poor to decent at software. The most important thing Apple is good at is marketing, and your comment demonstrates why.
Can you please provide the demonstrable truth that Apple gets carrier approval for their updates (which are released simultaneously worldwide, sometimes new updates go out mere days apart, which is definitely not enough time for every carrier in the world to have tested the update to approve it.
And also links the news articles where millions of Apple customers stormed shops after updates broke their phones.

Apple has been able to become powerful in phone market. They enough power to push the carriers around, rather than the other way round. Therefore everyone but Apple has to have their updates approved by the carrier before they get pushed out. My comment was not pro-Apple. Merely pointing out the hypocrisy in how carriers claim they have to spend months testing updates for everyone except Apple.
And yet somehow Apple is able to push updates without carrier approval and this doesn't happen.
