-- Screen 15%-20% physically larger, some of which could come out of the current face plate, but making the device slightly larger would be fine with me.
-- Higher resolution, something in the 720x480 range (same as current 1.5:1 aspect). This is available with current technology and would really help the readability of small type due to better antialiasing. This combined with the above suggestion, while not really a lot more than what's currently there, could make a big difference in the complexity of what's possible on the device. For one example, the old favorite game Starcraft wouldn't work on the current iPhone, but it would with a slightly larger, higher-resolution screen. And there are many others.
-- CPU ~50% faster. While 3G and WiFi data transfer speeds can be acceptable, much time is still spent rendering web pages, and the interface frequently gets sluggish for me (switching apps or scrolling, for example).
-- Camera: LED flash, 3 MP. Optical zoom would be nice but I don't think there's room for it.
-- Camera flips a cover over the lens when not in use. Mine is getting pretty scratched up and it's affecting the photo quality.
-- 50% longer battery life. Making the box slightly thicker to accomodate this would be acceptable to me. With everything the iPhone does, it's hard for me to get through a day without the battery dying on me, and that's not even with extreme use like watching a few movies on a plane.
-- Removable battery.
-- Micro SD slot (guess what Apple, you can also sell these in your store). They could sell a single iPhone model with perhaps 2-4 GB soldered in for the OS and minimal user data (fewer models helps control inventory), the rest would all go on external storage of whatever size the user chooses (or none, if they don't need it).
-- Bluetooth accessory connectivity (like for fold-out keyboards).
-- External LED light indicating email, voicemail, or other update received (different colors).
-- Boot a Mac from the iPhone via Firewire, or use in target disk mode.
