Gone are the days when people go frenzy over bling/diamanté DIY stickers and what not. For an updated look, go for the punk/grunge conical studs. All you need is 1 piercer, 40 pieces of studs with screw-ons and 1 rubber iphone4 cover. The tricky part is you need to have accurate eye for alignment on each piece. TIP: Put on some prescribed eyewear if you have to and make sure you pre-plan the positions. You don't wanna regret only after you pierced through. Have a go with this idea! The only flaw about this is I cannot have my phone in my pockets anymore. HA! One little sacrifice for the goth look. WHY NOT?
PS: That's my hand by the way in case you're wondering.
