Note that this information may or may not be exhaustive.
It also may or may not contain all known issues or good point about this device.

Freedom issues on the Nexus S (I902x):

• The hardware is proprietary.
• Some peripherals do require proprietary firmwares to work, some of which are firmwares loaded by the system
• The bootrom code (which is read-only by definition) is proprietary.
• The bootloader is proprietary and signed bootloader

Modem related:

• The modem runs proprietary software. It is loaded but not shipped by Replicant.
  • The modem has shared memory with the main CPU.
  • We are not aware of it being able to access the GPS, but it woulnd't be surprising if it still could (by having a direct connection to it).
  • Even if it has no physical access to the other CPU peripherals, it may be able to maliciously modify the main CPU ram to gain such access.
