Here's what I did...
First of all, you'll need the MobileFinder app.
1. Go into MobileFinder settings and change Application Launch to "Off" and System File Access to "On"
2. Navigate by hitting the ~ in the top right corner and hit "Up" in the top left until you're in the root directory.
3. Navigate to System>Library>CoreServices
4. Double click on SpringBoard.app. Since you turned application launch off it should lag for a moment then open.
5. Scroll down to near the bottom where you'll see several files, "SBDockBG.png," "SBDockBG2.png," and "SBDockMask.png."
6. Select SBDockBG2.png and hit File in the bottom left, then Copy, then Paste.
7. Select SBDockBG.png and hit File then Delete.
8. Double tap or tap and then hit Modify on SBDockBG2 copy.png.
9. Select the filename and change it to SBDockBG.png
10.Exit out of the program and restart your iPhone.
11. Success!
