It looks like the sleeving is different on the new SxC cables. The older cables that I have are marked like this
non-iMod (black and white with AOL written on the )
ALO Audio
iMod (black and red/orange with iMod written on the shrink wrap)
ALO Audio
The iMod SxC and the iPhone cable pictures you show look like they are the same cable. Maybe Ken can point out how to tell them apart?
