To those of you asking how to install it, I have a question for you... do you ever read the OP's first post? It is almost ALWAYS included with instructions, tips, and tricks.
You have got to start reading through everything because it can save you time and stress if you just read for any instructions or anything that is posted with successful tips.
I'm not mad, but seriously, come on, the instructions are right there. Here it is from the very first post of this thread:
FOR FLASHING ROM(S)
-boot into recovery via clockworks bootstrap
-select "wipe data/factory reset"
-select "Yes -- delete all data"
-go back "powerbutton"
-select "install zip from sdcard"
-select "choose zip from sdcard"
-find and select LibertyX/2-X.X.zip
-reboot
FOR INSTALLING THEME(S)
-boot into recovery via clockworks bootstrap
-select "mounts and storage"
-select mount /system
-go back "powerbutton"
-select "install zip from sdcard"
-select "choose zip from sdcard"
-find and select TheameName.zip
-reboot
It would also be wise to write this down, or copy/paste it into notepad or whatever for future references. Also, check back from time to time in case something in the instruction changes. Why? Because the phone's infrastructures can and probably will change from time to time and require things to be done differently at any given time.
