The second one. In the US they're a little hard to come by. Sure you can order something online. (There's a whole niche market of tiny dumbphones that don't claim to be made for prisoners, but are designed to be easily smuggled inside body cavities.) But their retail presence here is almost nonexistent.
Also, it's much more difficult to find one if you insist on a particular carrier. For example, the popular line of Blu dumbphones (which still have cameras) operate on 2G-only GSM, and don't work with Verizon, AT&T, T-Mobile, Sprint, or Boost (i.e. all of the major providers). You have to use something like StraightTalk or Simple Mobile (i.e. prepaid discount service, similar to Tracfone) to make them go.
