I am already aware of this feature since my iPhone 2g 😀. And does any one know that we can also search for a particular word in safari? (Find a word ) . In the google search bar just type the word you are looking for and there you will see as 'in this page'. Scroll down and tap the word. Voila!.
 
Cool trick thanks for posting.... I use to just start over every time I mis-typed a number. Those days are over.
 
Probably known as well, but when I saw this I tried it, and then held my finger down and got the copy and paste option. Did not know the calculator did copy and paste!!!
 
Nice tip for those who use the native app. For me, Digits and Soulver (I'll resume using this once they add iPhone 5 support) all the way.
