Since Dinoh must be out somewhere. I must respond for him and warn you that by hard modding your console you risk it being banned when going online.
And once you start the ban wagon it can get real expensive to keep getting back online. (buying new kv, re purchasing xbl, paying for stealth server services)
I have been extremely fortunate to have not been banned yet. ( I am certain my day is coming) So I guess what I am saying is if this is your primary console and you enjoy playing online then you may want to re think hacking your console.
There it was said. Just do your research and decide if it's worth the risk.
