I'm just skeptical enough to believe that the carriers are purposefully squeezing decent feature phones off their shelves so you'll be forced to have a data plan. There's two people in my house (wife and son) who have no need what-so-ever for data, but there's no feature phone out there worth a crap, so now they both have my old iPhones and ATT's lowest data plan.
It sucks AT&T forces customers to have a data plan. While we Canadians are usually jealous of your carrier plans and 2 year contracts, none of the carriers here forces you to use a data plan if you get a smartphone without buying a data plan. Sure you don't get the full subsidy but if you have a phone by any other means, you are free to use it on a voice only plan.
