  • Your opinion: Best protective case for an iPhone? It seems the Otterbox is the most go-to brand but does a Griffin case do just as well? What other brands work? I'm new to the iPhone world and I don't really want to drop and damage an expensive phone.
  • Which iPhone case is most protective? I have an iPhone 4 and my otter box is in need of replacement lol but I don't want to spend $50 on a thick case that's going to tear up in another month or two no matter how well it protects my phone. I want it to be skinny so it can fit in my pocket but mostly protective. Any ideas?
  • What is the best protective Iphone case that still looks good? I might be getting an Iphone but I want a protective case (one that looks good and doesn't add much bulk). I'm kinda clumsy so something with shock protection but is still sleek and stylish. I'm looking at the incase proslider and the speck candyshell flip so if you could also tell me which of those is better that would be great.
  • What is the best protective case for iPhone 5? I'm looking for a good iphone 5 case which will protect it from dust(especially the speaker at bottom), waterproof, shock proof and the screen protection. Please tell me a name of give a link to any of the above, would be best if it was all or at least dust and shock proof.
