Facebook has begun rolling out its free voice call service to U.S. iPhone users. The free voice calling feature was originally tested in Canada, but now iPhone users in the U.S. with the Facebook Messenger app can also use the service.

To make a free voice call from the Facebook Messenger app, just tap the "i" icon in the top right hand corner while viewing a chat with the person you want to call. You will be taken to the "Contact Info" screen that now features the "Free Call" option. The calls can only be made over a Wi-Fi connection, so don't expect to use it while on the road.

One of the most popular iPhone and iPad games is finally getting a sequel. Imangi Studios plans to release Temple Run 2 to the App Store around 11 p.m. EST tonight. TouchArcade got an early look at the game, and said fans of the original won't be disappointed with the new version, which turned out to be very similar to the first.

"I’ve been playing Temple Run 2 for the past day, and for the most part what wasn’t broke has not been fixed. Right from first boot up you’ll get a sense of deja vu as the camera sweeps in on the cursed idol that has been the cause of so much running over the past year and a half."

TouchArcade also noted the game has "received a big upgrade in terms of visuals and animation over its predecessor", and features much more fluid controls. Temple Run 2 also features new ziplines, an Indiana Jones-like mine cart, four different playable characters, and more attributes and upgradable abilities.

Waiting for the iPhone 5S to launch before upgrading? If a report cited by AppleInsider is right, you won't be waiting too long. Apple is said to be readying for March production of the iPhone 5S, with a scheduled release date in June or July 2013.

The report comes from research by Jefferies analyst Peter Misek, who states that there are currently two Apple prototypes being tested. One of these devices is the upcoming iPhone 5S, while the other could be a rumored low-cost iPhone model set for initial launch later in 2013. Misek estimates that Apple will sell up to 44 million iPhones during the current quarter.

Apple's rumored low-cost iPhone could feature a "chassis mixed with plastic and metal" instead of the reinforced glass or unibody metal used for the current models, according to a report by the DigiTimes.

Bloomberg and the Wall Street Journal both claim Apple is working on a $99 to $149 “entry-level” iPhone to "attract customers in developing nations". It also believed the more affordable iPhone will be made available in the U.S. sometime this year.

Previous rumors have suggested that the new iPhone will feature components from older models, a 5-inch display and a new exterior design. The possible older components and plastic body would help Apple keep the cost down for the new model.

Remember the iPhone Bumper case? Apple sold millions of these in various colors to help iPhone 4 owners protect their devices. Not only this, but the company gave many of them away for free and sent customers refunds to help solve antenna problems. Now ZAGG has updated the bumper with its Perimeter case for iPhone 5.

The iPhone bumper never looked this good. ZAGG has crafted a light, translucent case that minimizes bulk and maximizes protection. The Perimeter case has a slightly raised side, so when you lay the iPhone 5 down on its front or back the device is fully protected from scratches. The aluminum bezel and sides of the iPhone 5 are also protected, completely covered by the Perimeter.
