IPhone 4 Contacts Disappeared After Receiving Text Message

The title is a bit sensationalist.

The last reported instance of this happening in the linked forum thread is August 25th, 2011. Does iOS 5 suffer from the same problem? If so, I'd expect there to be new posts in the thread.

I was a little confused by the chap who'd addressed his gripe to Steve Jobs[1] (what kind of echo-chamber do I live in? Are there really customers oblivious to his passing?), and then I saw the dates of the posts!

FWIW, in my personal experience, I've rarely seen anything solved on the Apple discussion boards unless it's an extremely trivial issue. For e.g. I (and evidently many other people) have been struggling with getting with iTunes Home Sharing to work between a PC and an iPad, and the boards are filled with people asking around, and all 'solutions' have basically involved "have you tried turning it off and on again?" (which is a crapshoot).

But then again, the Nokia discussion boards are pretty much the same , so... shrug.

This was breaking news... in November, 2010.
