I walked into my local AppleStore, they told me no unlocked SpaceGrey64GB SE. But I saw on the website that I could pick one up if it was a T-Mobile SIM'd phone. After talking to the AppleStoreDood, he said worst case it wouldn't be unlocked, we could give it a shot. Bought phone outright, then I swapped my iPhone5 T-Mobile SIM in the store and got a message on the phone that I needed to call T-Mobile with the EIN numbers on screen, yadda yadda. Of course I didn't have a phone, even though I had 2 in my pocket. Stopped at T-Mobile store on the way home, waited and waited for long time, I decided to continue fooling around with SE. Well activation information screen never came back, I got sick of waiting so I finally gave up and left for home since they were busy.
Got home, plugged into iTunes for restore, phone reports it was unlocked! Tried to make a call and it worked! Glad I didn't have to wait for shipping!
