A Technological Twist From Apple: Two iPhones Unveiled Now news about our iphones tonight, apple unveiling not one but two new phones, one cheaper than ever before, the other faster than ever before, and a way apple beliefs your finger print could change your life. Abc's neal karlinsky tells us what this is. Reporter: For the first time ever, apple's latest and greatest isn't a new iphone it's two new iphones the 5s and the 5c. Not one but two new designs. Reporter: The new iphones sport better cameras and power for games and graphics. The singular feature is security, something called touch i.D. Touch it. You'll get the feedback. Reporter: It's all about security. Instead of entering a code or password, all this requires is a finger print to remember who you are and unlock the phone. Seems cool but other companies are racing ahead in the bells and whistles war. Samsung has a phone that can literally react to your eyes watching the screen. The killer app for apple's bottom line may be the iphone 5c, a cheap version for masses. While apple remains strong at home, it's being trounced by android phones overseas, including the holy grail of emerging markets, china. It's a big acknowledgment that they need to provide a low end affordable solution for a much bigger market. 5c for color or china. Reporter: All part of the race for dominance in the smart phone wars. Neal karlinsky, abc news, cupertino, california.
