Good morning. For some reason, I am suddenly not getting 4g service. I was having trouble obtaining a data signal over the weekend, but since have restarted a couple of times and pulled the battery. Phone seems to be running fine otherwise, but am only getting 3g, where I've always gotten 4g. I have done the ICS upgrade and the phone had been running quite well. I'm in Columbus, Ohio, if anyone else is seeing this issue locally. Appreciate any thoughts.
