If you have a Sony Xperia SP (C5302/C5303) or Xperia T (LT30p) with an unlocked bootloader then you can now download the leaked Android 4.3 firmware update that we reported on yesterday. For the Xperia SP, this leaked ROM relates to build version 12.1.A.0.256, whilst for the Xperia T it relates to build number 9.2.A.0.278.
The leak comes courtesy of DooMLoRD and follows a bunch of screenshots for both devices that were leaked last night. DooMLoRD confirms that the firmware was for brown (developer) devices but he managed to get them to boot on red (consumer) devices. Click the source links for further information.
