[Q] rom used here?

---

hey people

got a question..
noticed that in the series knightrider they use a x1 (+1 for xperia)

but in this one episode you see a call screen that i have never seen before!
maybe some one can tell me wich rom it is or what shell it is

kinda like this one allot! (just hoping it aint video editing)

see atached file

First screen is from an iphone.. Exactly the screen when you receive a call on an iphone

2nd is video edited
