Phones = modems, like the connection between two systems (Matrix/Zion) - but not to the outside world. (That’s how I feel.)
I think of the Matrix as running on a “neat and clean” corproate machine, and Zion as running on a hacker’s computer where things are messy, but they work.
I imagine Neo will figure out how to multiply himself at some stage, I think he and Smith have a lot in common by now.
FOOD.
I’m glad others have remembered that Neo pocketed the candy instead of eating it. I hope that gets re-incorporated.
Nobody eats food without a physical change happening - be it internal (e.g. the chocolate cake), or external - doors have a new backing.
Leastaways, not that I have noticed.
Okay - so the Merovingian drank wine and went away for a bit.
But the Oracle eats her candy and leaves by a door.
Seraph eats his noodles, fights Neo briefly and they leave - by a door.
I don’t remember the last time that anyone else ate food - although Neo was given plenty of offerings.
They don’t even snack, or drink.
What up with that? Or is eating just too unimportant to bother with?
Imagine if only those who ate food were the real people in this situation!
Oracle, Seraph, Merovingian, Neo. (And the Chocolate Cake girl.)
Bring back the white rabbit, I say!
One more thing - I would be delighted if halfway through the third movie, the screen just went THAT shade of blue… and stopped there.
Highly unlikely, and guaranteed to annoy everyone else! 
Either that, or just a sudden blackness with a little white flare in the centre that dies away…

And there’s the glorious Dallas escape route - Mr Anderson wakes up and realises it was all a bad dream… to the sound of a ringing phone.
