I got my orange and white today as well. I must say they are well made, I don't have a white bumper to compare it with, but i do have a black official bumper. The white oem feels a bit slippery in the hand, while the black official feels sturdy. Also the black bumper is a bit loose, while the white oem feels very snug. However, since it fits snug the cutout for the headphone jack looks slightly oval and not round like the black bumper. You really don't notice it much, also on my black bumper i can't see the matte screen protector line. On the white oem i can see the line, it doesn't cover it like the official bumper does, again not a serious issue. Also noticed it comes in the original black bumper packaging.
however my orange bumper, when placed on the phone, by the headphone jack it sticks up and doesn't lay flat. the white oem doesn't have this problem but the orange does. also the oem buttons stick out compared to the official bumpers which are flat and blend with the case.
Overall it's not bad for 10 bucks, however i might still buy an official white apple bumper anyway, this isn't a bad alternative though. now for the pics, i only have my phone taking pics so i can't provide pics of the bumper on the phone, but believe me the white looks fantastic on the phone, while the orange not so much.
