I ran uSwitch Broadband Speed test on the PC, and immediately after on my iPhone (using the uSwitch app). PC got 3.5 Mb up, 0.20 Mb down. iPhone got 6.7 Mb up, 0.36 Mb down. The iphone is connected to my SureSignal box, which is attached to the router by ethernet. So both use the same router, same local loop etc. Why does the iPhone acheive double the speed of the PC. I am guessing the PC is limiting the BB speed I can achieve. But I never see on evidence of this in the suggestions the experts/BT give to improve speed.
