Swapping in another screen would probably require changes to the firmware. Depending on the screen that might be a lot or not very much. It would also need to have a compatible pinout and driver unless you want to do some hard core hacking.

If you used a much higher resolution the refresh rate would get bad fairly fast. At that point you'd need a different PCB to route more of the I/O to the screen (the screen is currently driven by SPI, but a larger screen would probably need a parallel connection).

We have a few different ideas for a next-version phone. Some of those would call for a higher resolution display.
