Hello. I have had my 8220 for about 5 days now and have experienced two issues. I changed the theme to precision silver from precision t-mobile. tried changing it back, but could not get it to revert all the way. certain features of precision t-mobile came back, but not the color. I wound up wiping it clean and starting over. fixed the issue, color came back. also, developed a sim card error yesterday, powered off and back on and problem fixed. anyone know if these issues have been reported and if i should be worried? thanks, robert.
