Re: Spot on, ElReg.
A phone it may be - I own a nice bakelite rotary phone, which _may_ fit in my backback, certainly not any type of pocket, and it sure qualifies as a phone.
But such a monster is not a _mobile_ phone. In summer, I tend to carry zero bags, so trouser pockets it is. And avoid tight jeans so I can carry a phablet? Get lost.
