Some bottles were frozen solid in the freezer, some werent frozen at all. But as soon as we opened it, it would freeze from bottom to top and get maybe one drink. Also, we were in Iraq and the outside temp was anywhere from 110 - 140.

The bottle is under pressure because the water has expanded as the temperature was reduced. Pressure lowers the freezing point so when you open the bottle and reduce the pressure, it freezes. Its temperature remains the same.
Water acts differently to any other matter. It expands when heated or cooled from its maximum density at 4C.

It has to do with pressure.
The freezing temperature of water decreases as pressure increases.
Water also expands as it freezes.
Say that the water bottle is full to the top. As the water begins to freeze, it can no longer expand in the bottle. This raises the pressure and lowers the freezing temperature keeping it a liquid. Now you have a sealed bottle of water at, say 28 degrees. You open the bottle and rapidly decrease the pressure. The water can now expand and it's freezing temp raises back to 32 degrees. I freezes almost instantly.

All refrigerators and freezers have hot and cold spots. It depends on the type of container, how much liquid is in it, what the air-to-liquid ratio is, how much is in the fridge/freezer, etc, etc, etc.
P.S. Though I don't believe for a second that you're in Iraq with nothing better to do than to write such a question, I will take this moment to say, "Thank you", to all who *are* there, and who have sacrificed their time, if not their lives, and of whom, I am certain, would love to have the time (and safety) to type such questions.
