All iPhones are the same no matter where you buy it. The iPhone on the pic is either broken modded or not an iPhone.

  • Will my iPhone camera and apps work in England? I'm going to England for 2 weeks on Tuesday and was wondering if the camera and apps will all work. I don't care about the phone or texting part. Its an iPhone 5 and I have Verizon btw. I'd like to put pictures on Facebook and Twitter/update status/tweet etc. From my phone as well without having to use a computer.
  • Will my iPhone 4 work in England? I'm going overseas this summer and fall for studying, and was wondering if I can have a contract over there, keeping my same iPhone. My carrier is Verizon.
  • Why are iPhones so much more expensive in england than america? I was just browsing around on the Apple site, and I was having a look at the iPhone 5 when I realised that I was on Apple USA site not the UK, and switched to the UK site. The iPhone 5 on the US site said from $199 but when I went on the UK site it said from £529! That is like $788 dollars! Why the hell is the iPhone 5 (and basically any iPhone model/apple product) so much more expensive in the UK? 199 dollars and 788 dollars is a huge difference.
