I have to say, this may be the one thing that drives me away from Windows Phone to the iPhone. I love my Lumia 920, just like I loved my Samsung Focus, but I had really expected Microsoft to have learned from the update problems that plagued WP7. I know that they have made some improvements, and I certainly feel that Portico was released in a timely manner, but now we're back to the same story with (what I presume to be) carrier interference. At least with Apple you know there is a yearly update cycle and it's handled directly by Apple instead of going through the hands of the provider.
