So it's being reported that you can "slot a phone" into the physical Pip-Boy object. Is there a specific type of phone this was planned around, or are they aiming for general purpose, all phones are welcome type thing?

Sorry if that was better explained during the presentation video, but I think my mind was having a stroke from over stimulation with the rest of the fallout 4 news.

It appears to come with multiple foam inserts which you shape to your phone. The question was asked in the wrap up at the end of the stream.

Sweet, thanks for the info
