Anyone see this: Fostex AR-4i (http://www.fostexinternational.com/docs/products/AR-4i.shtml)
Stereo mic ins to class compliant USB audio for the iPhone 4. It actually used to be advertised for the iPod Touch 4G too, but that appears to have been pulled. The video is pretty cheesy... Now if someone could make an S/PDIF input for the iPhone/iPod...

If this uses USB to connect to the iPhone 4 - Would the USB adapter work on the iPhone? If it does I would think the Sound Devices USBPre 2 would work with the iphone 4 - since it is already supported with the iPad.

It looks like in iOS 5 apple may allow use of the iPad Camera Connection Kit with the iphone 4. Which would allow one to connect USB audio interfaces (i.e. the SD USBPre 2 to the iPhone 4.

I hope they don't remove this capability in the final release!

In principle you're right. I've been following this ever since I found out that stereo line ins on the the 4G iPhone and iPod Touch had been eliminated and replaced with a USB input. It's why all the stereo mic addons to the older versions of these models no longer work on the 4Gs.
Only through the Camera Connector Kit (CCK) can any class-compliant USB device work with iOS but Apple has decided that this kit will only work on the iPad. This thread on Gearslutz (http://www.gearslutz.com/board/music-computers/486958-ipad-camera-kit-audio-interface.html) that has a number of people reporting various USB audio devices working with the iPad + CCK, including the MiniMe and a Nagra MX, and I'm pretty sure the USBPre would work too. But there are three problems for field work: the awkward form-factor of the iPad, the delicate connection of the CCK, and the fact that any device connected this way must be self-powered as there's not enough juice to power a converter from the device.
In fact, the power issue is a likely reason why they disabled the use of the CCK on the iPhone and the iPad, although I personally think this choice is also motivated by marketing. Technically if a unit is self-powered, it shouldn't put any strain on the device's power requirements. I read somewhere that beta versions of iOS 4 had USB input enabled in the code for all devices but that it was disabled on the smaller devices on release. I'm very curious to see what the AR-4i kit brings to the table, and if it is in fact class-compliant USB audio; it could possibly wedge an opening for the few of us who want to use these devices as quality audio recorders, and maybe bit buckets.

We're leapfrogging replies! ;D
That's great news! I'm hoping it'll work with the iPod 4G too. And it's about time...

There are OEM Camera Connection kits that have USB in and out, a memory card slot, and a AV jack all on one adapter. So these kits may allow you to power the audio device, iphone, contain a recording SD card, and connect the audio device all at once.

If you read the single review posted for that item, you'll see that it doesn't work. I've looked at the SD and USB CCK teardown pics and there's a lot of electronics in those little plugs. Check this picture out of the USB CCK connector:

The main links to that site are down; you can change the pic number from 1 to 7 to see other pictures. And here's the SD card CCK connector teardown. (http://www.ifixit.com/Teardown/iPad-Camera-Connection-Kit-SD-Card-Adapter-Teardown/4129/1)
Clearly we'll have to use Apple approved hardware.

Well that kinda sucks... It would be nice to somehow power the iphone/audio device through the same connector.

All is not lost! The iAudioInterface2 (http://www.studiosixdigital.com/iaudiointerface2/) doesn't use the CCK and can power the iOS device when it's powered. It's entirely possible that someone could make a direct connection to USB that also powers the iOS. I think iOS 5 is finally going to crack all this wide open. I'm hoping someone makes a 30-pin to USB-B + power connectors that will let any class-compliant device connect to any iOS device. Oh: and make it compact and rugged for field work too. ;)

I ordered the AR-4i yesterday for my iphone 4s 64GB.
Will let you know how my 1st concert as videotaper worked out .....in 2 weeks.

Great sound!
You can also use it with Tascam's app called "PCM Recorder" or "FiRe2" in case you want AUDIO only (in 16bit 44.1kHz).
