-Pen Tile matrix arrangement means you're not actually getting a 800x480
Pentile was only used on the original Nexus One or the Super AMOLED HTC Desire. The SLCD variant of the HTC Desire had the full RGB display.
And sub pixel arrangement has nothing to do with display resolution. All phones that didn't use AMOLED screens had full RGB sub pixel arrangement, and that's quite a few outside of the iPhone.
-Apple quadruples its original resolution within the same screen size. No Pen Tile arrangement.
Pentile arrangement and Apple's display resolution have nothing to do with one another. Apple could have used Pentile sub pixel arrangement, given you the same 960x640 resolution on an AMOLED screen made by Samsung. They chose to stick with LCD.
-720p is laudable. If you want to count as innovative then be my guest. But to me its not as remarkable. But thats just me.
Same with Apple's "Retina" display. It's just an evolution towards high resolution phones that have been on-going for years.
Guys, there's so many things the iPhone brought to the industry, why even cling to this ridiculous point that is easily proven false ?

KnightWRX has the earliest example of a high-res display I can find but here are some more "not" on Android:
Neo 1973, running OpenMoko, announced in 2006, finally shipped in July 2007, 285 PPI screen. Not as good as the Toshiba Protege G900 and though announced earlier, shipped a month later.
A lot of the high resolution phones early on seem to be Windows Mobile 6.x devices.

High-res displays were already here, regardless of Android or iOS.
Exactly, dunno why some insist on saying "Apple spurred" anything here. If anything, there were rumors Apple was bringing the Retina display with the 3GS because of the industry trends and a lot of us were disappointed when the 3GS had the same 480x320 resolution as the 3G and original iPhone.
