This update has been nothing but a pain for me. My phone constantly reboots, that is if it will even come on to be able to reboot. I'm lucky if I can get it to come on for 5 minutes before it will shut off again, and then take hours to be able to come on again. I have taken to the store and they have flashed it for me, that didn't work. Resetting it didn't work either. Of course I am out of warranty and I can't upgrade for another 6 months. So I had to file an insurance claim on it today. I love my phone and I'm really mad that this happened after they pushed the update, it was working perfectly fine before. I can bet you that my replacement phone won't allow them to push the updates to me, I will do them manually to avoid this problem again.
Good luck to everyone having issues. It's so frustrating!!!!
