Has anyone had any experience replacing the custom pigtail coaxal cable for the wifi/phone antenna with a U.FL pigtail? It looks similar, but I can't tell the size by the photo alone.

If you have a laptop you can open up the wifi card slot and have a look at one, nearly all laptop mini-pci wifi cards use those connectors to conenct the internal aerials however I think that the iphone one is smaller than a standard connector.
