weird iphone problem

[riprse]

suddenly my iphone wont load the avforum & 1 other forum i use regularly. i have no idea why. i have been using my iphone to access and post on these forums ever since i got it but for some reason it will no longer load them, i keep getting the message, cant find server but when i try to go on any other site its fine? its just these too. i have not changed any settings and can access these site on my pc from the same wireless network my phone is using.
any ideas this is driving me crazy.

The only time I get the "can't access server" message is when I haven't typed the URL in correctly. Have you checked that ? If they are book marked I would still check to make sure they are correct.

i sometimes get that message, but i think it's when i don't have a good signal. i had it this afternoon in the living room, but moved across the sofa and it worked fine and i even made a post on these forums. i have a couple of individual forums bookmarked for easy access

if all else fails, try emptying the cache and turning the phone properly on and off

tried all of the above. even reset my phone but it still wont work I think the phone will have to go back to the shop its started to freeze and becomes unresponsive. this is my second iphone since Xmas. im not impressed. I love the iphone but if I have to change it again your looking at 3 phones in as many months.
