Saw this today. From the job description:
Location Kansas City, MO
Member of the Carrier Engineering team that supports taking products through technical approval at the carriers. A Carrier Engineer team is responsible for day-to-day technical interactions with the one or more carriers to track down issues reported by the carrier, assist the carrier with testing they might be conducting and working with program management, software development and test teams to get products approved by the carriers.
Combined with the rumors floating around, this sounds like a Sprint iPhone is a possibility. (Note: Sprint is based in the Kansas City area, hence the Apple job posting.)
Sprint will definitely need the iPhone if the AT&T/T-Mobile merger goes through to stay relevant, so this could be very good news for them.
EDIT: here is a screenshot, in case Apple takes it down.
EDIT #2: welcome, MacRumors members! While you’re here, I invite you to browse the rest of the site and find out more about usage caps and the T-Mobile merger
EDIT #3: looks like Apple changed the job posting. See the screenshot for what it used to be.
