I am not sure if it is part of the ROM or part of the theme, but sometimes when on a call, instead of the traditional phone handset in the status bar, I get what looks like a roaming icon. It's an empty signal strength logo with a small R in the upper left hand corner. I live in a cery good coverage area, and it only started since rooting and theming. Best I can tell there are no roaming charges on my bill. Is this a known feature? Is this telling me something else, like peak vs off-peak or something?
