Now we already know iOS 5 contains more than 200 new features. iCloud service is one of the biggest selling point of iOS 5. Users can back up their equipment on iCloud various types of data, and can use this function to find your own iOS devices and locations of your friends. One of the most noteworthy is the Notification Center, which allows a user to easily view and manage the location notice. It also includes a device that allows iOS users to send each other text messages, photos and video of the new information services iMessage; and the new newspaper and magazine subscription Newsstand. Powerful software allows you to convert WMV to MP4 in a few minutes.
iCloud: Back up your calendar, email, iWork documents (sorry, Microsoft Office), phone contacts and more, and access them all on your iOS 5 device, your OS X Lion-, Windows Vista- or Windows 7-equipped desktop, or via Apple's slick Web interface. iCloud also remembers your past App Store purchases, so deleted apps or songs can be re-downloaded easily. Each iCloud account comes with 5GB of free storage; can be purchased right from your phone. Most syncing requires a Wi-Fi connection and that your iPhone be plugged into a power source, so it's not completely wireless, but close enough for most.
Photo Editing: The new photo-editing capabilities that are built into the iPhone's standard camera are minimalist but workable. Now, when you click the Edit button in your Camera Roll, you can crop, reduce red eye, or auto-enhance an entire photo. These features aren't nearly as in depth as other photo editing apps, such as Adobe's free Photoshop Express, but are great for touching up a picture on the go.
Twitter: If you're not already a Twitter user, iOS 5 may make you one. Twitter is everywhere on iOS 5, including on Maps and in the Safari options menu, and it looks gorgeous. When you're setting iOS 5 up, Apple even asks if you'd like to download the official Twitter app. Sorry, Facebook.
iMessage: Your iOS 5 friends can now reduce their text message plans (if your carrier hasn't eliminated that option, like AT&T did) by using Apple's BlackBerry Messenger look-alike that functions essentially the same as SMS but doesn't work against your reserves and can include "read" receipts.
Quick Camera Access and Grid Shots: You now have instant access to the default camera by double-clicking the home button on your iPhone's lock screen. You can also use the volume up button as a shutter and use a grid overlay to stage your photos. If you are ipad user, you may need youtube downloader for ipad, get more useful information from here.
