Nice program except for the minor detail that it BRICKED my phone!
Iphone 4, ios4.0.1, comex jb, cydia, rock, standard repos, NEVER install vwallpapers!!!!!!!! Beware

Same thing happened to me. SSH into phone and get rid of anything Skrew and vWallpaper and you should be ok!!!

I had the same problem!!!! It wouldn't let me go to springboard it would freeze, so I called it and when I was in the middle of the phone call I hit the home button and was then able to go to cydia to delete. This worked, I tried respringing about 15 times. After i did this I never had a problem with it again.
