I have had my iPhone 5 since June of 2013. It was fine until about 2 months ago. It would go from LTE to 3G to 1x for no reason. It would not automatically connect to my wifi, and at times, I couldn't send a text message. I took it to Best Buy, I bought their insurance, and of course once I got there, it worked fine. That was 2 weeks ago and now it is acting up again. Anyone else have this issue? What did you do? I'm really starting to miss my android right now.
