Don't get me wrong - I said catastrophic failures, as in bricking the device or making it totally useless after the update. I am fully aware that PR1.1 surely has its own quirks, that's the nature of software development - you fix some bugs, you introduce some others... Bug-free software will never exist, at least not software that is used on a mass-scale. As for the SIM problem with `3` cards, Nokia acknowledged that from the day one of the release, so you probably knew what's in store for you when you bought it. They promised they'll fix it, and they obviously did, but, at least in your case, with some additional problems. This, of course, doesn't mean that they shouldn't find a way to provide a downgrade for the cases where new problems render the device hardly usable, or where cons overweight the pros. I think I already made myself clear on that.
