I bought a skin from iCarbons (iCarbons — iPhone 4 Black) that looks pretty sweet if you ask me.
Doesn´t protect very much if you drop it, but you wont scratch it.
it seems very expensive, do you like the Cartoon style skin,such as Angry birds, or Hello kitty ?? my friend bought one pcs just $3.33, is cheap, but useful....
I like the idea but I think that making use of skins just take away the beauty of the iPhone, but no offense meant to those who are using and sporting one. Just for my personal preference, I think that iPhones would look a lot better without them and could totally make use of the glass panel to its full emphasis.
But as it in any case, the thing you are going with is on the basis of to each his own, so we could just say much about what we have on our own.
