Well, when you flash a ROM, it's like doing a hard reset. Everything you have on there will need to be reinstalled. Thus, make sure you have back ups of everything you want to keep if you do decide to flash. It's not a problem, and flashing can really make the phone a LOT better. It is a bit scary the first time you flash (at least it was for me) but once you get comfortable with it, it can be a lot of fun to upgrade. I personally recommend Lyorite's ROMs and if you can figure it out, SASHIMI is great for installing all of your programs and settings after you flash.
