Edge-to-Edge Screen
All of the newer iPhone models are expected to have edgeto-edge displays, according to blogger John Gruber of Daring Fireball. I would love to see the display take up the entire front of the next iPhone, since there's a decent amount of screen real estate that current models simply aren't making use of. The full display with a flush Home button would make for one classy looking iPhone, especially if the rumored allglass design turns out to be a new feature too.
