Someone please help me! Basically I have an iPhone running 4.1 that I want to use as an iPod touch BUT I still want the iPhone status bar to have the at&t signal bar rather than NO SIM or NO SERVICE. I've tried several things such as changing the no sim into iPod with fake carrier and then using the att4ipod theme but it doesn't work. It'll still say iPod rather than the signal bars. Can someone please please help me?
