Fortune did some digging through the Apple job boards and uncovered a listing looking for cellular systems engineers who are familiar with the CDMA and WCDMA protocols, along with GSM, EDGE, GPRS and HSPA. AT&T doesn't use CDMA radios, but Verizon does, of course. And if the Verizon iPhone is, in fact, on the way, they'd probably need a few people to help work out the final kinks. Then again, maybe they just want a few people who really know their shit. [Fortune via Boy Genius Report]
