I just noticed that the text selection tool changes if you double tap and hold instead of just tapping once. It'll change shape and allow me to select a range of text starting from the word I originally tapped onto. (See screenshot.) Tried it in both Mail and Safari Safari was a little bit more fickle about it than Mail; you had to wait until the magnifying glass appeared before tapping again. Is this new to iOS 5, or did I just never notice it before?
