Another hints points out the possibility of the iPhone coming to Sprint network. This hint was noticed by the website Stop it, AT&T and later reported by MacRumors, the hints is in a job listing that Apple put up looking for ”Carrier Engineer” in the area of Kansas City, Missouri.
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.
This might be a hint of Apple working on a Sprint iPhone because Kansas City is not a typical place for Apple’s Engineering and Sprint is based in the Kansas City area.
