Until the iPhone passed it in the second quarter of 2011, the Motorola RAZR had been the best-selling cell phone of all time.
Motorola debuted the ultra-thin flip phone in 2004. It immediately smashed through sales records and remained the top-selling cell phone for 12-straight quarters.
Its run came to a screeching halt in the third quarter of 2007, when Apple debuted the iPhone.
But during its streak, RAZR flew off the shelves faster than the iPhone: Motorola sold 110 million RAZR's in three years. It took Apple four years to sell as many iPhones.
