pre update
I had possibly one random reboot prior to the update...I would sometimes lose data connection and have to reboot...this seemed to only happen when I turned on WiFi. If I turned off the wifi I would have to reboot the phone to reconnect to 3G. I live in a 3g area only. After the update, I will have days that I notice 3 or more reboots. Some days, I may notice one or none. It is very random.
