Which one's better?! Is it faster/more responsive than the Hero? Does the Zio support live wallpapers? I really like the hardware of this phone, they way it looks, but I really, really like the Hero's HTC Sense! That's sort of unique about HTC phones, while they rest of phones, even from different manufacturers, their software pretty much look the same? Specially weather animations!!! It kinda sucks that the Zio doesn't have dual camera function, nor does it have flash! I don't have a Sprint Store near me, so I can't really go check out the phones. What do you think?
