$6.99 at time of purchase ($7.99 as of 09/07/11)
I own the original iPhone so this didn't fit it perfectly because the 3G is slightly larger than the original iPhone.
With a little bit of tweaking getting it on the phone wasn't a problem.
As of today, 09/07/11 I still have the back decal on my iPhone but have removed the front decal because I put it on top of a mirror screen protector and it wouldn't come off cleanly.
Highly recommend this as an old school protector.
