It's not that much bigger. Maybe 1/4 - 1/3" more in height and width, is all.
More space seems to be given to the screen:
Code:EVO 3GS Res 800x480 480x320 Screen [SIZE="4"]4.3" 3.5"[/SIZE] Height 4.8" 4.5" Width 2.6" 2.4" Depth 0.5" 0.5"
uhhh it is a lot bigger and makes the iphones screen look tiny... its almost a whole inch bigger... I'm hoping for the new IPhone to do the same size 4.5" or so... looks really nice!
OH AND P.S. That scroll Wheel is outrageous!!! try putting that in your pocket every two seconds without it breaking... thank god iphone dont have something like that!
