I have managed to get the update from 2.3.1 to 2.3.1p5 working,
but like you say, it takes a long time to complete.
And i have used the 2Gb image, i think is gonna take a while longer for the 4Gb image.
I have also the feeling that 2.3.1p5 is still verry unstable, i have opened another topic about
problems with timeout errors at boot, and corrupting after reboot or shutdown.
