hi, bro Copernicus. thank you for responding.

for the Phone apps, it is true, nothing rotates. after booting up for the first time, the system can rotate, but after it loaded the apps, it just flip back to landscape.

all of the apps work fine even though they are stuck at landscape only

here I enclosed my transitions.ini

# This file contains timings and values for transitions in hildon-desktop
# duration = time in milliseconds
# zoom = amount to zoom out the background. 1 = none, 0.5 = zoom to half size
# radius = radius of blur (this is actually the number of blur iterations,
# so the bigger the number the longer it takes)
# saturation = the amount of colour left in the background (0 = grey, 1 = normal)
# brightness = brightness of the background (0 = black, 1 = normal)

# -- zoom_duration: the number of miliseconds to spend on zooming

btw, bro. is PR1.3.1 filename is RX-51_2009SE_21.2011.38-1_PR_COMBINED_MR0_ARM.bin ??
if yes, then i've already installed it, but the issue still persist. can you help me to format everything in my N900?
