I am sure most of you know this, so just ignore if that is the case, but I have seen some people (and I had the same confusion at first too) say they don't like that you can't choose contacts like we could in the previous version of the Android OS on the Bionic.
So open up your phone and click the phone icon to bring up the dialing screen.
Once there, bring back your memories of good old T9 typing and press the digits with the letters of the persons name, so in this instance, I was looking for Cole Johnson, I typed john (5646) and it brought up him as a possibility. I could have also type Cole (2653) and it would have done the same thing.
There is also a search option but is annoying. This way, you just T9 the persons name and bam, there you go. Hope this helps anyone out there that is or was confused.
