For the record, I own my own phone (Android), but I have an unlimited plan with AT&T that includes unlimited text and talk that costs me $150, because my plan covers three phones that I pay to cover under the plan (including my own). It's one of the conditions that lowers my rent and utilities where I stay.
To each his or her own, of course, but I want to see a plan where anyone on an iPhone can have unlimited talk/text for $35, that's not bundled with other services.
