I know this has probably been covered and I have done a quick search with no joy. Ever since i've had my iphone 4 i've noticed incredibly slow wifi. Its not my network as my macbook, iphone 3gs and ipad all run off it at its true speed. Ive done side by side comparison checks with my 4 and my 3gs, with these being the only devices connected to my network for the purpose of the check. My 3gs wins by at least 3 seconds to load up a page. And as for checking my mail its mind numbingly slow. Is anyone else experiencing these issues? for your info my 3gs is running on ios4.
