I've been looking for it for a long time .... a FREE card scanning OCR app for iPhone...
Now with LinkedIN's aquisiton of CardMunch it has arrived... CardMunch using Mechanical Turk is set to change the landscape of cardscanning for business professionals. Card Munch uses artificial artifical intelligence i.e. real intelligent human transcriptions, not OCR; so forget about wasting your time correcting all those horrible OCR errors, its no longer necessary.
Check out LinkediN CardMunch for iPhone ... its great, try it...
