The new iPhone features several improvements that enhance your everyday experiences. It works faster with built-in wireless LTE technology; it sounds better with three microphones and noise-canceling technology; and the photos are even more flawless with improved HDR and a new panorama mode.
It's also longer, thinner, and has better resolution. This changes how you view websites, emails, mobile apps, and other content on your screen. Apps that don't accommodate for the extra screen space have black bars at the top and bottom of the screen.
Since millions of people all over the world are buying the iPhone 5, our event app developers optimized our apps so they adapt to the bigger screen for a better user experience. A better mobile experience = happier attendees.
