Under the old OS under the power option we had the option to go from NORMAL to HIGH PERFORMANCE turing on 4G. WTF...where is it under ICS?
Never been in 4G since upgrade.
After ICS, my rezound would not go to 4G and no data access except thru wifi. I just uninstalled my task killer and power saver apps. After restarting the rezound, I now have 4G.
