What cool stuff should i do with a dummy iPhone 5?
Okay so basically, due to my impulse buying, I have a dummy/non-working plastic iPhone 5 and I don't know what I can do with it.

In class work go on it then when they ask for it cause you shouldn't be on it they will be fooled.
Trick your friends
Leave it somewhere see who takes it
Be creative
Keep it

  • Would this be a good dummy/toy? So lately my brother has been using my phone and iPod. I thought that getting him a fake plastic one would keep him from taking my phone. WRONG! He complained, saying it was plastic, but was fine with it not working. So, I figured getting some cheap parts for assembling a dummy iphone 4 (home button, screen, back, and a weight in it to add for real ness) so I've been saving money and got enough for it. Is this a smart idea? Or am I wasting my time? (He's 12 years old with autism.)
  • Where to buy really cool iPhone cases? I've seen a picture before and it's of all these different types of cases and they have them in different colours? It's like in a shop? DOES ANYONE KNOW WHERE THE SHOP IS OR WHAT IT'S CALLED?
  • Where to buy a fake dummy iPhone 5 (besides ebay)? I don't want to use it as a phone in anyway, I just want a dummy iPhone to pull a prank, lol. So is there a place I can buy it instead of off eBay? Thanks! Ah, let me rephrase that, Not online. Aha.
  • What would be a good iphone 4/4s (Amazon) to be a good test dummy? So I want to try to replace a iphone screen, and since the iphone 4/4s would be a good candidate, since it's hard to replace its screen, I would use one of them. But since I have a phone that's in Like New condition (been in a otterbox in addition to screen protectors) I don't want to use it. Can some one help me find a good phone to test on?
