No that's not working. It's disabled in my W200i. So I am doing the trick I read in a tutorial, but that's done with setool.
Okay, here is the little tut: ( made by alexherdea )
Changing the normal screensaver , with a flash one.
The shortcut* of the flash file goes to : "tpa\system\settings"
The flash file goes to : "usb\other"
At the end , u make a ZIP archive of both things ( togheter ) , put it in Misc , and after press Flash in Se-tool
Because w200 doesn't allow us to put flash files as screensavers , we must create a tweak for that. First , a shortcut that contains the address to the flash file. After that , the phone will put as default the flash screensaver choosen by u. If u don't like the flash file located in the zip Archive , don't worry , u don't have to reflash to gain another one. Just pick some of u're favorite flash files , and upload them to "other" folder in the phone . Then , rename them into "iphone" , and that's it , next time u'll lock your phone , u'll see u're flash file set as screensaver ( wallpaper as flash not recomanded , because of meny meny bugs )
I added the files, in attachment.
