If you are in the United States and didn't get to pre-order the Pipboy Edition of Fallout 4, then you're pretty much out of luck An update on Bethesda's blog has announced that it is sold out in North America. If you're in Europe, then you still have a chance to get one.
They did update on the phone size that the PipBoy will support. IPhone 6 and Samsung Galaxy S5's seem to be the largest and there will be phone inserts as well as customizable inserts for all sizes. If you are like me and have a Samsung Galaxy Note 4, sorry.
Fallout 4 is going to land on your PC, Xbox One, and PlayStation 4 on November 10, 2015.
