Ive used 3 cases now,
the incpio case? (the one ATT sells its rubber with a plastic case around it)- that one constantly tore so i just had enough of it.
the wave case (comes in a 2 pack and its plastic) scratched my phone and then broke
now i am useing an incase which i love BUT it really drys your hands out...everyone looks at me stupid when i say that but its true!
Seidio Innocase II. I also have a Incipio feather case, but I only used it once, and will put it up for sale soon. I like the chrome protection this case offers and the exposed apple logo on the back. The Seidio Innocase is the only case for me!
