Most phones can do it. Unfortuantely, after thinking about it, most cellular data plans are closer to the price of broadband (if not higher), rather than dial up. You'd be better off buying a low-end broadband connection and a cheap wireless router.
If you use dial-up for connectivity on the road, you can either get a cellular data plan (and use your phone or a USB cellular adapter) or just buy the USB modem from Apple.
