I want to make a list of all ROM's available for the Optimus M here. Send me a link to them and which OS they require on the phone to start (2.2 vs 2.2.1 vs both). I will make a list of them here and categorize them. This will make it incredibly easy for people looking to get creative with their phones to find some options 
. Thanks everyone!
2.2 ROM's:
RomZero Final
2.2.1 ROM's:
Slide ROM
Both:
