You know, if you are new to all this, just read read read! You will learn so much just by reading. If you want to know something specific, do a search. You will learn a lot more & understand if you study & learn what you want to do with your phone. Then after you have read the stickys & guides, the words flying around will at least sound familiar. Then you can say, I want to do "this" & read "that" & I still don't understand. For instance, I'm rooted, but I haven't changed ROMs yet because I cracked my laptop screen. I finally ordered a new one yesterday so today I'm going to be reading & studying ROMs, themes & how to partition my sd card. Then if I have questions, I know who to go to for help. You do know not to ever use ROM manager with these phones right? Unless you want a ruined phone as a paperweight.
CHOOSE HOPE & NEVER GIVE UP!!
