Update. After the update, I started out great but noticed some back and forth between 3G and 4G where before it used to be a strong 4G signal. Then the radio would pretty much freeze after leaving or turning off WiFi. I would have to restart the phone to get a data signal back. The airplane mode switch would work intermittently. so I contemplated doing a factory reset, but before I tried that, I decided to remove battery, SIM card, and SD card and left the phone like that over night. I had done a quick battery pull after the update, but figured I'll try it again and this time just left it like that for about 6 hours.
I put everything back together and my phone seems like a different phone. No reboots since updating, but I was only getting one about every week or so. Data connection is back the way it was and hand off between WiFi, 4G, and 3G is seamless and better than before. SMS is MUCH better with no more pauses and delays. Phone seems snappier and my battery life is damn good, giving me a good solid 12-15 hours with active time in the solid 2.5-3.5 hour range (lots of texting and push email, about 10-15 short voice calls, minimal gaming, internet use, and GPS) before seeing yellow. This is maybe 1 hour more than what I had before. I'm also leaving GPS and Bluetooth on all the time now where before I was constantly turning them on and off to preserve the battery. WiFi still drains the battery if left searching for a signal, so I turn that off before I leave the WiFi area.
Yes, my GPS blanks out every few seconds or so when looking at it through GPS status, but it hasn't affected my navigation, Google maps, or location setting, so I don't care. It locks on pretty quickly between 1-5 seconds and doesn't seem to drain my battery while active as much as it used to. Before, while searching for a signal and even after locked on, my battery level would drop like my truck drinks premium. But now it is great.
The update screwed around with some of my setting like ring tones, volumes, some sync settings. Played havoc with my mind until I realized this... LOL.
Loving this phone more and more.
