@Fast-Dammit! I go thru the trouble of, ya know, using my brain and stuff and kinda sorta figure out this root thing. Then here you are with this incredibly clear, concise, awesome post. You Sir, owe me a bottle of Excedrin Migraine.
Thank you! This is great, I'm ready to jump in now.
re: App2SD- There's a very good chance I'm wrong but I *think* that is a feature of Froyo. Just root or root and OMJ's ROM may not be enough?? Happy to be proven wrong on that.
