Can i decorate my iphone 4 otterbox case?

I recently got a new iphone 4 because my other phone was stolen and to punish me my dad put an ugly black otterbox case on it and told me to never ever take it off or bye bye phone. I'm thankful for my phone but avsolutely hate that case! I was wondering if there was a way that i could paint over the silicone, plastic-y material and make it girlier or put glitter in it or something. Its the only case i can get so i can't mess up… Any ideas

But stickers on it

Here are some cool decals:

  • What glue shall I use to decorate an iPhone case? What glue should I use to stick flat beads/rhinestones onto my plain, plastic iPhone case? I really don't want the beads to fall off if I was to think about selling them. Here's a pic of the kind of case I mean: And here's a pic of something I'd like to do:
  • Should I buy an iPhone 5c or decorate my bedroom? Okay so I have been saving and I have just enough money for an iPhone 5c, I currently have an iphone 4. Now I have just swapped rooms with my sister and I need to decorate it, so I need everyone's opinions on what should I spend my money on.
  • Is there anywhere I can find a cheap Otterbox Preserver Case? I went on amazon and ebay, and I found cheap otterbox armor cases, which are almost the same thing, except that it doesn't work on the iPhone 5s' fingerprint scanner, while the preserver does. If you find anywhere that the case is cheaper please tell me.
  • Iphone 5 case otterbox commuter or slider case? I really like these two cases and i want to get one of the two. I know lifeproof is good too but it covers too much of the phone.
