Ive have a modded 360 but only for single player games due to banning.
Buy used and abused not worth loosing a warranty from M$. M$ will eventually catch up to newer versions of mods out there so banning is inevitable.
My mod is so outdated that some games don't work...at least the xbox is still going strong for 2 years now.
I dont know what mod i have either sorry, it was done by a mod shop in the city. Id look for soft mods, at least the sticker wont be tamperd with from opening but when you return the xbox for repairs, if so, just say u got the 3RLOD. They usally just send you back a refurb one.
