The all new iPhone 5 was launched on September 12, 2012 (watch the keynote here). With a better processor and a bigger screen, iPhone 5 offers few more opportunities to app developers to harness the new hardware features. Although the iPhone 5 (which comes with the new iOS6) has a native integration with Facebook and Twitter, there are a host of other apps (free + paid) that are definitely a must have for the iPhone 5. This article lists out ten must have apps for the iPhone 5. Although the article is particularly directed towards the new iPhone, all of these apps are also compatible with iPhone 3GS, 4, and 4S.
