Before I get too deep into ROMs and kernels, let me give you a quick breakdown on the must have root apps. Some of these apps I live and die for. Literally, I don’t know what to do w/ my rooted phone without them.
Root Checker (Free)
This is a must-have for 1st time rooters and even for the veterans messing with different kernels. The name of the app basically is exactly what it does. It checks if your phone is rooted and if busybox is installed. [Market Link]
