I need a USB 3.0 connector for my PC

Hi,
In your case I don’t think that you are able to use the iPhone browser without the iPhone, because Normal browsers are expecting some facilities, but the iPhone browser won’t provide that facilities to use it separately.
Window kit of the iPhone driver is not matching with other browsers. It is not specified the 320 x 480 in size and also there is another option which other browsers don’t have is the maximum expendability of the scrolling option.
And plugins will not compatible with the normal browsers.
If you really want to run the iPhone browser separately just visit this site, they sometimes will give you an answer for this.
But the probability of the solution may very low but just try out.
