I have an important question since im a noob

just released a custom firmware. My question is what does this custom firmware do? Is it like jailbreaking and will I be able to host mw2 lobbies with this custom firmware. I am running 3.55 right now and want to host lobbies so can I? I don't know if this is the right section but can anyone please help me.

Can anyone answer me please!

Hi,

if you had actually read the post on the front page it tells you your answer not to mention its also been asked and answered many times in the comments.

at the moment other than being able to install signed pkg it does nothing the original firmware dosent do.
