The firmware upgrade is included as standard on all models shipped after January 2012 (all PLED-W500’s manufactured with a serial number beginning SL11201).
All PLED-W500’s manufactured in 2011 will need to have the firmware upgrade applied in order to enable Wi-Fi capability.
Wi-Fi capability is also possible on Apple and Blackberry platforms and the set-up instructions will be similar although slightly different.
