I'm getting 1mbps on my iPhone 4 according to the speed test app while on my computer I get 10mbps according to speedtest.net and 24mbps according to speak easy. (Perhaps there is a MBps and Mbps disparity, not sure for the reason) but either way I can easily stream anything on my computers while on my iPhone I can NEVER get a youtube video to show. My 3G is faster than my wifi on my iPhone as sometimes I'll load a HQ video from wifi then switch to 3g and it will stream fine. What on earth could be causing this? I have an airport extreme.
