I read a rumor that Apple pushed this update to work around Qualcomm patents so they can keep selling iPhones in China. Would explain why the update appears rus

  That would make a lot of sense. I bet they've re-written big chunks of the LTE stack in a real hurry to work around various patents. Mobile standards and modems are a massive kludge of compatibility layers and hacks. Just look at the 'Hacks' section of the mediatek modem engineering app and you'll see all kinds of tweaks to allow the phone to connect to a certain network in a certain country which does something slightly wonky. My guess is that hurried rewriting of bits of a mobile stack probably led to them not perfectly replicating all those hacks, so certain phones with certain combinations of base stations, mobile networks, sim card models and authentication servers no longer connect properly. On the plus side, most of those mobile networks will probably now be snowed under with complaints from angry iphone owners, so rapidly updating their systems to become compatible again, even if apple refuses to re-implement the hacks.
