I thought I knew the differrence, but I was not sure how they play a part on a phone's system, which is what I believe is a flash (RAM) drive.? When I see people refering to different roms, what are they referring to? Are different roms just tweaked operating systems that small changes were made to the code?

If I follow the guide at the link you gave me, will I be able to adjust the amount of space used for storage versus computing power or will it be set at a different, yet predetermined level?

What will be different on functionality other than speed from a factory phone?

If I screw up my phone, is there a guaranteed way to get it back to factory settings? (using like a "ghost" software before I begin?)
