Apparently blarkKABOOM people have examined the new Apple iPhone SDK launch material, and have looked into it so thoroughly that they discovered a little piece of information that they presume Apple didn’t wish to be known.
What did they find? They found a search icon in the contacts application which would be a great feature should you have a very long contacts list on your iPhone. So it could be possible to have this search feature available, however the search icon feature is only in screenshot concerning the v2.0 firmware, and strangely missing from the video presentation. Well perhaps Apple aren’t quite ready to announce it yet, as we all know just how tight lipped Apple can be don’t we.
