It really isn't that hard to understand guys. The update now does the top as opposed to the bottom.
This update was never meant to fix the reception issue that some are experiencing when holding the phone. And it won't be fixed by a firmware update, because the problem appears to deal with the
hardware of the phone. Apple can't change the hardware design of the phone through a software update. This update is simply going to correct the amount of bars that you see that show your reception, because apparently the old algorithm to do this wasn't right. It's now more accurate in showing you what your true signal is. And it didn't make your signal worse. Your signal always sucked, it's just now not lying to you and saying that it was better.
