That is not a feature of the iPhone. If you are searching for a contact, then search the contact's name, not their number. And before you say it, yes I remember T9, which was all there was at that time, which is much easier to search a contacts name than to try and type in a number. I don't see it coming back, but you are able to provide feedback to Apple here if you wish to see that feature. www.apple.com/feedback/iphone.html Doesn't mean you will see it, but that is the only way Apple uses for feedback.
