Find out ROM version I just got a Galaxy Nexus and I want to revert it back to it's original condition for starters ( I'm talking about the software ). I noticed I have ClockworkMod installed, does that mean I have a custom ROM installed?
ClockworkMod is a custom recovery software. If you want to revert to the original ROM, then you can download the official ICS ROM for nexus and flash (install) it if you donot have a backup taken previously of the phone. And AFAIK, you can still root your phone again on ICS and then the phone will again be at your command (you can even install custom APKs). Also you can try a file manager like, Astro File Manager which I personally haven't used it but you can get it from marketplace and use it to install non-market apks by simply transferring the apk over usb to sd card and tap on the apk.
