Guys and ladies, What combination of skins or cases are you using or will you be using for your new iPhone 4? Personally, I'm thinking of using a invisishield/bestskinz for the back glass, and a Apple black bumper (unless I can find one cheaper sooner). I might even do a gelaskin (but it doesn't have a warranty like invisishield) and combine it with a green bumper - just to mix it up. Not quite sure... Anyways, I would love to hear your recommendations and ideas. Even more, let's share pictures! And tell me where you got your cases/skins from! Thanks!
