New Facebook app designed with iPhone "5" in mind?

After playing with the new Facebook app (which is tons better than the previous one IMO), I feel like the app designer either messed up or actually designed the app with the new taller iPhone in mind.
Look at the size of the compose boxes. There's so much space waste on either side and after starting to write a few lines, it's really difficult to see anything else on the screen. Of course, this behavior will be just fine on the new iPhone which is slated to have a longer screen.
What do you guys think? Is the Apple/Facebook collaboration closer than we think? Could the Facebook engineers have any knowledge about the next iPhone?

Here are a couple of screenshots.



Even the way text is handled when you look at a picture full screen makes me think how much better it would be on a taller screen.
Anybody else?

 

What I'm saying is, this updated app will make more sense on the new iPhone with bigger screen. On the 4S it actually feels weird and like a step back when it comes to the size of all the comment boxes.
Just an observation.

 

On a side note, has anybody figured out how to tag somebody in a picture that's uploaded thru Instagram?

 

Absolutely. I think Facebook is one that will look even better on the new iPhone! In my opinion it's the perfect solution: same width but additional viewing space for more content. Win!
