OK, this is gonna definitely sound way noob, and I probably am, compared to most here, but...I keep hearing this phrase about ROM Trimming. 1. WHAT is ROM Trimming exactly? 2. WHY would someone trim a ROM? 3. WHEN would someone determine it was a good idea/necessary, to trim a ROM 4. HOW does one trim a Rom? 5. WHAT effects can/does ROM Trimming actually have? Please forgive, but I don't understand the term...and Wikipedia was no help.
