You need to update the radio and the system separately.
You want to grab the signed-dream_devphone-ota-142608.zip package in
addition to the radio (notice the 'ota' part in the name).
The instructions for both are the same:
-copy as "update.zip" on the SD card.
-boot while pressing the home key (~15 seconds)
-alt-L to display the console
-alt-S to update from the SD card
(and there might be more instructions on-screen when flashing the radio).
