    Does it use usb 3.0 to connect to the computer, or still using the old 2.0?

    "It’s as yet unknown whether Lightning will, in the future, support the new USB 3.0 spec – the current Lightning to USB cable supports only USB 2.0. This would require 4 (instead of 2) data pins, which is well within the connector’s capabilities."

    If you're right, it's amazing to what lengths Apple will change a device but still not change something that would be useful and backwards compatable because originally usb 3.0 went against the thunder$bucks connection.

    USB 3 doesn't matter in the iPhone.

    Just because it has flash memory doesn't mean that it's secretly a 500mbits SSD that does email! The iPhone can't even max USB 2's transfer rate, so don't worry about USB 3.

    I'm sure it can transfer data faster than usb 2.0. I've seen transfer rate on wireless at 1MB/sec. So I could see it reading data that fast. With a 64GB iPhone transfering about 50GB of music files is very LONG time on usb 2.0.

    This is probably true, or iPhones wouldn't take so damn long to start up. :p

    Yes. iPhone flash memory speed is about 20 mb/sec.

    While the 5 is USB 2 I bet Lightning is USB 3 (and maybe Thunderbolt) forward compatible. So the next iPhone (or iPad) could be USB 3.

    The question is why would it matter. The port is there mainly to sync your phone to your computer and USB 3 really won't impact the sync that much - just my opinion

    I wouldn't be surprised at all if sometime over the next 5 years, there's a Lightning/USB 3 cable. Or a Lightning/Thunderbolt cable. And you'll be able to plug that cable into whatever 2012 generation iDevice you like. But you'll still get less than USB 2 speeds. Because the device itself is the bottleneck. USB 2 can handle 480 Mb/sec, or around 30 MB/sec in real life. And most likely the flash memory and interface controllers can't handle anything faster.

    I'm sure the geniuses at Apple could have out a fancy blue USB 3 end on the current Lightning cable. But then everyone would be bitching that their phone was only transferring data at USB 2 speeds.

    1 MB/second is around USB 1.1 speeds (12 Mb/sec). So I'm not sure what your point is.
