lol... i forgot i posted this ... ok let me post evreything...
first download all the 13 files with the name of planeshift
http://www.box.net/shared/neqph3x1gothen if you dont have a program to install skins use ctheme (that is also on the box) and install it on the transflash card not the cellphone of using motomidman. Once your see your phone restarted, close the motomidman program and unplug your phone from the data cable. Now switch your phone's USB connection to "Memory Card" mode. (on your cellphone go to menu, settings, connection, USB settings and change it to Memory Stick). now open your cellphone from "my computer" and create a folder called skins, then create another folder inside this called "Planehsift" and there paste the 13 files you downloaded, then unplug your cellphone again go to aplications and run ctheme, install the planeshift skin and turn off your cellphone and then turn it on again... and enjoy your Ps skin
PS: if the skin doesnt work paste the 13 files outside the folder Planeshift, inside the one of skins.
Btw i didnt choose a background you must choose one yourself xD ...hope it works for you
