Apple is notifying the first researchers who will be receiving these special iPhones as of today, and the Cupertino company says that the devices will be sent out right away. Under the terms of the program, participating security researchers will be provided with iPhones that are on loan for one year, though it will be possible to extend the loan period.
The Security Research Device (SRD) is intended for use in a controlled setting for security research only. Shell access is available, and researchers will be able to run any tools and choose their entitlements. Otherwise, the SRD behaves as closely to a standard iPhone as possible in order to be a representative research target.
