Root Downgrading 2.3.4 to 2.2.1 Gingerbread question! Please Help :-)

[CloSetCaSe]

Well its my first time with droid and im planning on downgrading from 2.3.4 to 2.2.1 to root and remove bloat ware. But what i wanted to know is there a custom rom like Gingerbread 2.3.4 cause i really like the battery life and layout im quite use to it. But im not sure what a rom is or does or even where to start looking not easy for me to understand. As many options as i see out there i dont want to make a mistake cant really afford to, not sure what different sense's there are and what not just need a simple noob answer lol... Looking for any suggestions... Thank you

CloSetCaSe, there are plenty of ROMs out there for the MyTouch 4g (HTC Glacier) and you can surely bump back up to Gingerbread after root. I recommend after rooting to back up anything important with Titanium Backup, then grabbing ROM Manager, both from the Android Market. A great Gingerbread ROM for HTC Glacier is CyanogenMod 7.1, and if you would like Android 4.0 (Ice Cream Sandwich), I recommend Creamed Glacier (WARNING: Still in BETA). Hope I could help
EDIT: ROM = Read-Only Memory btw
