We’ve spent a lot of time talking about Apple’s new Assistant which is expected to be one of the headlining technologies shown off at the October 4th event.

The video above is the work of artist Jan-Michael Cart who was contacted by MacRumors to put together this concept video of Apple’s new iOS 5 feature that we detailed just a few weeks ago.

Below is another artist rendition showing off what the Assistant interface might look like based on sources with “knowledge of the feature”. We can verify that these are relatively accurate including the purple swirl around the mic which our source saw in a prototype device. Remember this can also be used from the lock screen as well.

Last night we detailed that Apple’s new iPhone will come in three different configurations –including a likely 64GB model – in addition to the 8GB iPhone 4 which hit Apple’s inventory database last week.
