Hi i am very new to android but i am pretty savvy with technology but just not familiar with the android lingo i recently got a GNEX coming from and I4S for the sake of hopefully learning how to customize and teeter things to the way i want by learning what a ROM is exactly and how to flash them and know my way around android. i've never rooted but i plan on doing so and was going to use nexus rooting tool and then from there learn how to flash on JB. so what im asking is there a better tool to root and whats a stable ROM for JB i read that cyanogenmod seem to be pretty popular so any help or suggestions would be appreciated since i am a noob to android . also i be checking out the root and rom forums so if there is good threads in there let me know thanks
