Hello Android forums! This is my first android after being a costant iPhone man! Yea I know sorry! But I just bought this optimus M from metro pcs and it came with the 2.2.2 firmware! Is it safe to downgrade this to the rootable 2.2.1? And if it is can someone please direct me to a good tutorial? And another noob question the ROM that people install on these androids are these a custom Operating System? Thanks
