sorry if this has been asked before, im still new to the jailbreaking thing. How do you change the lock screen theme? I have downloaded this theme http://macthemes.net/forum/viewtopic.php?id=16806816 and can not figure out how to get it on my phone. i have spent quite a bit of time trying to get it to work, and it doesn't seem to install. any help would be greatly appreciated. even if you pointed me in the correct direction, im not sure what i am looking for online either.
