FYI this from A&K when I asked if they would make a 30-pin cable for the AK10:
Dear iriver customer,
Thank you for contacting iriver customer support.
When the AK10 gets released, it should have various cables such as the 30-pin cable that would be compatible with older Apple devices. If you have any questions or concerns, please email us back at any time.
Thanks & Regards,
CS & Tech Support
