best protection?

so i have a brand new k810i and was wondering what kind of casing overall works best for it.

i ordered a crystal clear hard casing for it. and a SPUC screen protector.

but ive seen those silicon casings as well.. any opinons about any of these items?


also, if i did use a crystal case for it, does it reduce the visibility of the screen?


one more question just to throw out. how can i get AIM on it. i doubt there is a java enabled program, but im pretty much always on AIM..


thanks in advance
