I had bosspaper when I originally had the iphone 3gs jailbroken. After going through the long wait to rejailbreak, I reinstalled bosspaper on the new 4.0 jailbreak and I can't seem to get it to work. I think it may have something to do with winterboard, but I have it hidden.....I don't know. I'd really appreciate some help if anyone out there has any ideas.
I now have it working. I found a fix by googling. You have to download the bosspaper transparent doc. from cydia and enable it in winterboard. Works perfectly.
