I find it rather difficult to see what public shrift about such issue would add to anyone. Except potentially giving an impression that there is something seriously wrong with whole hw-design, even if most users don't experience such problems.

Communications can easily be turned against you, as we have already seen in this thread - transparency should be something to improve things in community, so it's quite sensible to deliberate communications. Also, I doubt that community concentrating on issues like SIM-cards won't improve anything since those issues are completely out of community's hands. Therefore only sensible way is to just say, contact care and have it fixed.
