 It's pretty easy and shuts it up there is no data cable required and it's easy to do. I wouldnt mess around in these menus to much or itll cause some errors on your phone unless you know what your doing good luck.

First step
Ok so step number one is going to be getting a data cable this is the worst step because it requires spending more money. Ebay works for a place to but heres another page for the Data Cable  I suggest buying the most expiencive one it come with drivers and all the other stuff that will make life easier mine is on order so I we cant go to much more into hacking the phone except there will be a guide up for some basic stuff that you dont need a data cable for. Hopefully this is usefull and will be able to grow. I am hoping to get my own space within maxedmobiles.com and I'll be able to be more resources full there.
