I am having a difficult time with the connection of 3G. I have full signal, but I don't have the connection. I've resetted my phone 4 times and did an update on it and briefly it'll show the 3G icon but then it'll disappear. I've had nothing but problems on this phone and I have had this phone for less than a year. This is a replacement phone. Another thing is that I keep on getting duplicate text messages. Has this issue been resolved? I am getting extremely annoyed. What can I do about the connection problem?
