The iPhone 3g is no doubt a great invention. Its also rare as can be right now. So you don't want to do something to mess it up right? Well, then like everyone else and like phones you had in times passed, get a case! Everyone would like to NOT have one, so they could get the full look/feel of the iPhone or iPhone 3g. Invisible Shield came up with a concept like that. Even has a lifetime warrenty. So, I like that product and bought it, I still don't have my iPhone, yet. AT&T has it on back order. The only thing is, if you drop it, it may not get "scratched", but a thin lining around your iPhone will not absorb the impact. Internals might get damaged. Plus, even though its a case, you don't want a nasty scratched one, so Invisible Shield can tolerate certian things like keys in your pocket rubbing against it, and still not scratch the wrap. Agent 18's Eco Shield, I'm not a tree hugger so I don't care about all this GREEN crap which isn't helping us anyway, just to make yourself look like you're doing charity. Sorry, back on topic. Their case is exactly what everyone is looking for if you don't want it on your belt. Protect and No added bulk, but with no screen protection! I'm curious, though, does anyone know if the Eco Shield will fit over the Invisible Shield? That was my question. Just wanted to also talk about the aspects of both. Keep in mind, the FULL BODY INVISIBLE SHIELD for iPhone 3g. That means the Front and Back coverage.
