Updated to ICS last night. Lo and behold I had 4G at my house!! Last week when I turned on 4G I could only get 3G. Same at work I am on a fringe are and now I have 4G in my office. However when I change back to 3G using LTE on/off the phone only goes to 1G!! I don't steam but am worried about power drain. Should I just leave LTE on all the time? Thanks!!
