Just read Cory's guide:

Just follow Cory's directions, take your time, give the phone time to do what it's suppose to do and it works fine. I did it and everything worked out fine. Now I just don't know what to do next. Need some help also.
Just received mine also. Could anyone tell me if their sales order number was different than the shipping notification order number? Mine was and I'm a little concerned.
