Next iPhone could read your fingerprints

The next iPhone could be reading your thumbprints. I'm Bridget Carey and this is your CNET Update. Apple pushed out a new beta version of iOS 7 for app developers to tinker with and there have been some interesting discoveries including hidden code for fingerprint scanner. A programmer discovered a folder called Biometric Kit UI which includes instructions for how to read a person's left or right thumb on an iPhone. That has people speculating that the next iPhone could have some sort of thumbprint security protection feature. Apple purchased a fingerprint sensor company a year ago, so it could be putting that tech into use now. Netflix is testing out individual profiles, so each family member can get their own usernames, recommendations, and set their own cues. It's being tested now with some Apple TV users and Netflix promised that these profiles will be rolled out across all products by the end of August. Also, in streaming news, Comedy Central launched an app on Xbox called CC:Stand-Up which brings 6000 videos from more than 700 comedians straight onto TVs On-Demand. The only catch is that you need to pay for Xbox Live to access the app, but you don't need to prove you pay for cable. Viacom executives say they're not worried about losing cable customers because this will just get people more interested in the network rather than hurt ratings. Before buying your next book, you should compare the prices on Amazon and Overstock.com. That's because Overstock is in a daring price war right now with Amazon when it comes to books. Overstock cuts prices, Amazon matches, then Overstock cuts its book prices even lower. While these two online giants fight it out, you might as well reap the benefits. And Sprint just expanded its 4G LTE coverage to 41 new markets across the US. Sprint has been lagging behind the other carriers with 4G LTE coverage, but now, the faster wireless speeds are available for customers in 151 markets, but there are still many areas without Sprint's LTE including Manhattan. Google has completely updated the Zagat website and released new apps for iOS and Android. For the first time, you can check out Zagat Restaurant Reviews for free without having to sign up, but not everyone is happy with the change. You see, only nine cities are available now on the Zagat website and apps, and the website is full of upset users who are now limited to what cities they can search for just because it went free. More cities will be added in the coming months, so keep watch for that. Google purchased Zagat back in 2011. That's your tech news update.
