If *that* is your only criterion, then you aren't in the market for something with a 800 by 480 pixel colour touch screen, are you? If they want to charge more than a fiver for it, it *has* to be much more than just a phone, so the choice of OS is going to be pretty important.
Re: does it make phone calls? Yes!
