A state-of-the-art SMSing feature, iMessage, pioneering cloud computing feature iCloud, great Twitter integration and a revamped Safari browser are the notable features of iOS 5. You will get all these features on your iPad now. You can send SMSs for free of cost to other iDevices, push the data automatically from your iDevices to cloud servers, enjoy matchless web browsing experience and Twitter integration on your iPad also. All these features are highly appraised by the reviewers. Apple introduced these features at its Developers Conference in June 2011.
