Good news, fitness freaks: Nike's Move app, which brings Fuelband functionality to the iPhone 5s using its M7 motion-sensing co-processor, is now available in the App Store.

Some new iPhone 5S are having battery problems. Apple told the NY Times, "We recently discovered a manufacturing issue affecting a very limited number of iPhone 5S devices that could cause the battery to take longer to charge or result in reduced battery life." Those with crappy battery life will get a new phone.
