Is the inside of the bag insulated for the the water bladder to keep cool?

No it isn't but you can buy extra cooler tube bag to keep the bladder cool

Will the front pocket fit my plus size iPhone?

We at Nathan do not feel this vest accommodates the plus size iPhone.

What is the size of the back zippered area? Not the one for the bladder. Will a larger cell phone fit into it?
