"customers also expect all the latest whizzy features to be supported on their new phone"
True, but this thread is about a previously working, preexisting, widely available feature . . . .
"note how all these issues are fixed by software updates by the head end manufacturers; that tells you where the problem really lies."
Maybe yes, maybe no . . .
The problem with my 4S bluetooth appeared when I updated to iOS6.0 and fully disappeared when I updated to iOS6.1.3. No firmware updates to either my 2012 Kenwood DNX9990HD nor to the MyLink (Panasonic OEM) in my 2013 Camaro. All the noise and finger pointing aside, Apple fixed this issue for me, so there must be some credence to my claims about customer experience. I'm not an engineer, and really don't care who created the problem. What matters to me is that it has been fixed by Apple.
"I've personally got zero stake in this game; feel free to purchase something else if you like, that's the way the free market works."
Absolutely (and I'm certain you'll do the same). But, if I buy another iPhone, it won't be because of your posts about superior technological standards and adherence to the purity thereof. It will be because Apple faithfully fixed my problem, and their newest product is more appealing than the alternatives.
