Ok so I got the iPhone 4 everything works great, i do beleave the iPhone 4 has wireless n and so does my router, so no problems there. But it seems to be very slow loading web pages, Facebook, when I download an app nothing appears for about 5 seconds, then it's says waiting for another 5 and then downloads very slow. If anybody could give me any help on this issue it would be great, also I have a silicone case on the phone, but I have also tried it without it aswell.
