Over black?
The iPhone is such an iconic design object that's marvellous to hold and play with, let alone place a call, but, does it's slick black finish really match 'you'? Urban Outfiitters have stepped in with a series of happy/edgy/cool artist designed skins to mash things up a little, and take the look beyond basic black. I've picked a couple of my faves below which totally have a decor vibe - Blue Willow by Colin Thompson which, yep, happily borrows from your Gran's china, and Bunny Blossom by Kozyndan totally feels like a vintage wallpaper (I see it working with a navy velvet sofa, pea green wingbacks, a glass waterfall coffee table and an oak herringbone floor - but that's just me...).
