To get the dock to be black in summerboard the General posted:
Open your wallpaper image in Photoshop, go to Image -> Canvas Size. Set clamp to the down arrow. Change it from 320x480 to 320x91. Save it as /System/Library/CoreServices/SpringBoard.app/SBDockBG2.png
I can't find that directory in my system. Went to Macintosh HD/System/Library/CoreServices/ but no Springboard. Is the I phone filesystem supposed to show up somehow? If so how do you get to it?
Thanks,
Bill
Oh, I mean save it to your desktop or wherever, then stick it in that directory on your iPhone. You'll have to read the many threads and tutorials on this site and elsewhere for information on how to get access to your iPhone's filesystem. I recommend the SFTP way.
