I think iPhone covers are a bit unfashionable, OK very tacky. I take particular offense to the transparent ones.
However, I was worshiping the Gods of kitsch when I found this. It's a tongue in cheek cover that turns your iPhone into a fake chocolate bar while protecting it as the same time.
It is really funny and made me laugh a lot. Just look at that detail in recreating the chocolate segments.
Of course, it also comes in a box, making it the perfect present. So perfect, in fact, I am going to try and think of a summer based Secret Santa type activity.
Whilst I was researching this trend, I also found this brilliant iPhone chocolate cat and swiss chocolate iPhone.
