My built in apps have disappeared, how can a person reinstall Safari, Siri or App Store on an iphone 4S?
I have lost my built in apps and do not know how to reinstall them on my phone. The Safari and App Store icons are gone. I can no longer surf the net on my phone and the little "microphone" key has also disappeared when I send text messages etc. I now have to actually type the message instead of speaking into my phone. Siri has also vanished. Any advice?
iPhone 4S, iOS 6.1.3
