Unconfirmed: Is A Fully White iPhone 4G On Its Way?

Pretty much everybody has seen the pictures of the upcoming iPhone 4G, but did anybody pause to consider the possibility of color options? While it’s hard to determine the authenticity of this, but pictures of what looks to be a white front cover of the iPhone 4G have surfaced. Sure, we’ve seen the white color iPhone 3G/3GS before, but that was only on the back cover, if this leak is accurate, we might be in line to see a fully-white iPhone 4G released. Do you think that it’s a possibility, or is this just some joke from someone with too much time on his hands?
