I ordered a Scoche clear/purple band from buy.com. And it came with clear front and back screen covers. I'm very happy with the bumper and I have received several compliments on how well it looks with my white 4S. I think I'm still gonna get zagged though.
Now this one I have an answer for.
Just got mine.
A cross between a silicon and gel case. Comes with screen protector, caps for jack and dock openings and fits like a glove. Pretty neat too. The volume and power buttons are also covered. Www.switcheasy.com.
They also have a European site for any other old-worlders on the forum. Www.europe.switcheasy.com
Was also very happy with the UPS delivery.
Off topic I swear the UPS man knows me by name now the number of deliveries he's made since I became a full Apple convert last June after my iPhone 4 purchase last year. Waffling I know, just can't stop. ..
