I keep my phone in one of the velcro chest pockets and the iPod in the other. If it gets too cold I move the pod to the zippered pouch inside the coat. The velcro pocket inside is large enough for a small journal, wallet, and pen. The side pockets, although not sealable, are extremely deep. You can put a liter sized bottle of water in one and jog without the bottle falling out.
The coat is extremely warm. I have the optional fur lined hood and matching Arctic Bib Overall (which also has great pockets) and can sleep in beds made of snow in subzero temps.
