iOS 7 is completely redesigned with an entirely new user interface and over 200 new features, so it’s like getting a brand new device, but one that will still be instantly familiar to our users,” said Craig Federighi, Apple’s senior vice president of Software Engineering.

The new iOS7   has all the built-in apps  re-engineered for 64-bit, and  provides a seamless developer transition with Xcode® support and the ability to run both 32-bit and 64-bit apps.  Also provides deep integration with the new Touch ID™ sensor and takes full advantage of the new iSight® camera sensor to enable new features like automatic image stabilization, Burst Mode and Slo-Mo video with 120 fps.  iOS 7 is designed to complement the gorgeous exteriors of iPhone 5c, with matching wallpapers and translucency that carry the color through the entire experience.

With more than 200 new features, iOS 7 for iPhone, iPad and iPod touch includes:

• Control Center, which gives you quick access to the controls you want in one convenient place with just one swipe from the bottom of your screen;
• Notification Center, now available from the Lock screen so you can see all your notifications with a simple swipe, and the new Today feature gives you an at-a-glance view of your day with a summary of the important details such as weather, traffic, meetings and events;
• improved Multitasking that gives users the ability to switch between their apps in a more visual and intuitive way, and iOS 7 pays attention to which apps you use most and automatically keeps your content up to date in the background;
• AirDrop, an entirely new way to quickly and easily share content with people nearby;
• new Camera app filters so you can add real-time photo effects, a square camera option, and you can quickly and easily switch between your four cameras—video, photo, square and panorama—with just a swipe;
• a redesigned Photos app that introduces Moments, a new way to automatically organize your photos and videos based on time and location;
• full-screen browsing with Safari’s new redesigned user interface, the new smart search field helps simplify searching, and there’s a new view for your bookmarks and your Safari tabs;
• Siri with new male and female voices,* Twitter search integration, Wikipedia integration and Bing web searching within the app; and
• iTunes Radio, a free Internet radio service featuring over 200 stations and an incredible catalog of music from the iTunes Store®, combined with features only iTunes can deliver.**

Additional new iOS 7 features include a new Find My iPhone Activation Lock, that requires your Apple ID and password before you can turn off Find My iPhone, erase data or re-activate a device after it’s been remotely erased; FaceTime® audio for high quality calls over a data network; and new ringtones, alarms, alerts and system sounds.

With all the welcomed features, fans and users now fear if it’s worth it having to create or have up to 3GB to be able to download the software.  Millions took to twitter to express their concerns as one tweet reads – “So when U download this iOS7 w/this 3.1GB of space that U just happen to find, do you still have to space to add the things you deleted”? @wepluggoodmusic . Another tweets, “Trying to delete 3.1GB off my phone just for iOS7 !!! stressssed” – @ExpectGDThings

iOS 7 is now  available as a free software update starting on Wednesday, September 18 for iPhone 4 and later, iPad 2 and later, iPad mini and iPod touch (fifth generation). Some features may not be available on all products.
