I understand the ROM is the OS, the kernel is the interface, the radios are the drivers, but what is sense? From what I've read so far it sounds like it's, for lack of a better way of explaining myself, "bigger" than the OS. I'm rooted but got stuck before the nand unlock so never moved onto flash anything yet. maybe when I can set aside some time for it. What is sense? Is sense stock? What are the other options? Is there a comparison of all of the options somewhere that explains what is gained and lost in each? Thanks.
