Apple released its newest operating system iOS 5 on Tuesday, with  more than 200 new features, all compatible with the older iPhones, iPad and iPod Touch.

The new comprehensive operating system is totally independent of any device, so once the download is complete, you won't need cords to connect to your computer ever again and all information will back up and sync automatically with other laptops and iDevices on its own. It is free and can be downloaded from the application store.

Here are some of the coolest applications of the new iOS 5 apart from the much-touted and known features like iCloud, which automatically pushes all documents, apps, calendars, mail, contacts, photos and music to all of the user's other iOS devices.

iMessage allows iOS users to send unlimited texts to anyone who owns an iPad, iPhone, or iPod Touch, and the Twitter integration that lets you tweet links and photos from anywhere in the iDevice.

Other advances are the notification center that can be customized according to personal needs and the two brand-new mail and calendar applications through which users can write in rich text, indent paragraphs, flag messages and search the archive and create or manage events in the calendar.

And then there's the upgraded camera, parental control and Safari browser, but there is much more to it. Here are less-known, yet the coolest applications:
