A note about the above mentioned process of getting your MSL:

There are actually 2 different codes, the MSL which allows you into the phone as many times as you want, then the OTSKL which lets you in only once, which is what they might give you. There is no way to know in advance so be sure to do what you want to do while you are in there and do not just punch it in to test. If it works a second time then you got it
