    Quick thread question - what's the bandwidth of the connector?
    If Apple were to jump onto USB - What would be needed for a USB 3 to dock connector cable to work?

    Seemingly the time to launch has slipped a bit, so articles are pushing 2010 rather than 2009 for commercial products with it. In this article, Engadget says "that test specifications for the SuperSpeediest standard ever will be fully ratified by the end of June" - so could products with USB 3 hit, by the time we start seeing Arrandale?

    If the 30 pin is specialised on the 30 pin end, if it was USB 3.0, could the iPhone, iPod etc take in data faster? Or is there a bottleneck at both ends?

    I've seen some details here, but there might be better ones.

    well, im not a specialist but every usb device must have a usb chip controller so when plugged can inform the usb stack crucial information about velocity, power, id...
    indeed ipod has a 30 pin connector, usb only takes 4 of them, other are or reserved (maybe for diigtal audio, old firewire connection) they maybe build that connection to reduce costs on industry for all future apple products.

    its still a

    its still a standard usb . Just because it has a different end doesnt change speed.

    I believe it is 480mb per second

    My thought being when will Apple shift to USB 3 in terms of ports, and in terms of capabilities for iPhone/Touch. Would 901.11n be better than USB 2, then USB be better than that, real world results?

    What is 901.11n? Did you mean 802.11n wireless standard? If so, then theoretically USB3 should be much faster than 802.11n. Unfortunately not even USB2 lives up to its stated performance.

    That's why a lot of Mac fans love Firewire, for it's sustained speed.

    usb 2.0 is actually faster than ieee1394.

    and even if u do eventually get usb 3.0 on ur pc, it also would require the ipod to support it, otherwise it will just run at 2.0 speeds

    The overhead of USB 2.0 typically brings the theoretical speed below Firewire 400. I have have every peripheral plugged into USB 2.0 including cameras, hard drives, mouse, keyboard, iPhone and iPod. No device is getting 480Mbps, Firewire 400 would fare better under such a load (if the devices were available in Firewire). And of course, a revised version of IEEE1394 also covers Firewire 800.

    As mentioned, the dock connector can handle higher bus speeds, the iPhone would just need the new USB 3 controller chip.

    Looks like Apple could go with Bluetooth 3 for the iPhone, and also laptops by the summer - will they be an early adopter of USB 3 too? It seems that with Bluetooth 3, and the 802.11n potential for the next iPhone, they're in a very strong position to do wireless sync and more, with devices and Macs.
