$27 iPhone 5c

Starting today, Walmart will cut the price of the iPhone 5c down to just $27 with a two year contract, down from $99. It's no secret that the 5c hasn't been selling well; two months ago, Apple told its manufacturers to reduce orders for the holiday season. The sale lasts until the 24th. via Business Insider

Free Wifi

This week, Mayor Michael Bloomberg announced a plan to bring free public wifi to Harlem. The network will be the biggest free public wifi area in the country. The Harlem WiFi Network is expected to  be completed in May 2014 and will cover an area that stretches from 110th Street to 138th Street between Madison Ave and Frederick Douglass Boulevard. That's 95 city blocks! via Digital Trends

Spotify

Spotify is set to extend its "free" ad-supported music to mobile devices. Now, users can listen to music on their iPhones, Androids and tablets without paying the subscription fee. The catch? Smartphones will play tracks on automatic shuffle. via Digital Spy
