I think only the backlight LEDs might have a problem with 5V.
It says under the absolute maximum ratings section of that datasheet that VddMAX=5V (internally generated voltage) and VinMAX= Vdd+0.5. So I would think that 5V logic is ok as long as the power supply is at 5V also.
Where does it say that "the logic levels should be kept from 2.7V to 3.3V"?
Anyway, I haven't tried this out yet. I'll try and get it running at 5V with the backlight hooked up to the 3.3V on my uno.
No public wish lists :(
