slagman5, thanks for the mockups!
However, you forgot one thing, from my post... Look at how tiny the chin piece is on that 4-row mockup... What, you would hold the phone by the space bar? Talk about top heavy!
You need to have the room for the chin piece -- thus proving my point that by adding a 4th row, it would be absolutely
necessary to increase the height of the phone! -- maybe bringing it near the height of the iPhone 6, which is preposterous!
The chin piece on the 3-row passport is already too tiny (hence why AT&T increased it), so imagine making it even smaller (your mockup), that would again be like the failed Droid Pro! I returned that phone because it was soooooo uncomfortable + horrible OS, but design wise, it had many of the things we (9650 fans) were looking for as the next device (this was before the 9930 had come out). Here is a picture of the Droid Pro in case you haven't seen one:
