My name is Nate and I am from Iowa. I have had a Thunderbolt since a week or so after they came out. Have had issues with ring tones I set for people, when they call there ring tone may play or may not and I can't use one of my own tones for text or other notifications and now for the last update now the phone powers down whenever it feels like it. I have had enough of the problems and now am looking to switch to a different carrier because no one at Verizon wants to help. Just found out that it would be almost 600 dollars to cancel our contract, so I am trying to find anyway possible to make this phone work right. Please if anyone can help me it would be greatly appreciated, is anything out there to help or am I doing something wrong or something I don't know. Please help, any info would be great.
