The iDevices BCM20732I is flashed with the iDevices custom firmware during manufacturing.
It's the same physical module as the BCM20732S, which contains Broadcom firmware and is supported by our SDK (version 1.1).
Orderable PNs (can order through our franchised Distributors) include: BCM20732I and BCM20732IT (T&R)
Thank you! This helps clear things up tremendously.
