Hi,

The pixel density on your monitor is quite different from the one on your 
phone. Check out:

http://en.wikipedia.org/wiki/Pixel_density

According to:

http://en.wikipedia.org/wiki/List_of_displays_by_pixel_density

...the Nexus One has a PPI of 252.  That is, on one inch, there are around 252 
pixels and on your home monitor you may have around 80-110 (usually)...so 
there's the apparent difference in frame size.  To put in other words: the 
Nexus device has a higher resolution display than your computer monitor.

So...if the spec says the resolution is 480x800 you should be fine by encoding 
to those dimensions.

HTH,
Jorge
