If you were to prepare a list of most under-served smartphone form factors, portrait QWERTY ranks high on the list; few manufacturers have dared to dabble in it so far, despite the fact that there would seem to be a treasure trove of potential users in the BlackBerry realm who live and die by the Bold / Curve layout. Motorola has given it the most high-publicity shot so far with entries like the Droid Pro, Charm, and Flipout, and it looks like Samsung might be prepping a head-on Droid Pro competitor for Sprint thanks to some shots that have emerged on PocketNow today. We have precisely zero details on the hardware specs, the possible launch time frame, or really anything else at this point, but we'll keep an eye out.
