I got the 4.3 update yesterday from Verizon. Downloaded it and everything seemed ok. Woke up this morning and the green charged light was on but the phone wouldn't come on. I had to take the battery out to get it to turn back on. Then once it was back on, it kept restarting itself. It shut down and restarted itself about 7 or 8 times before it wouldn't come back on at all. I brought it to a Verizon store, and they took the battery out (duh) and the sim card out and back in and restarted it just fine. They told me to get stuff backed up just in case. Before I made it back to work, the phone was dead again and wouldn't come back on at all. I took the battery in and out about 10 times, and the sim card a couple of times too. No luck. Then, I ran back over to Verizon, they tried a new battery and some other stuff and couldn't get it to power up either. They called verizon and they are sending me a new phone, since no one could get it to turn on. Then, on my way back to work, I took the battery out again and it powered right back up. WT??? I got all my pics moved to my sd card. Going to back up everything else when I get home. Not sure what to do now, as I have a new phone on the way. I have a feeling there is definitely something wrong with this one though and it's just a matter of time...
