Im using the theme u mentioned... ne idea why my apps icon is the regular 4 squatrs instead of that cool 3d cube?? Everything else works
do a long press on your apps icon until a menu comes up that should have as choices, "Remove, Edit, Manage, Share". Choose Edit. A box will come up with the current icon, and a means to change what the icon does when tapped.
To change the icon, tap it inside the edit window. Then choose "ADWTheme IconPacks". On the next list that comes up, choose the appropriate one--if you're doing the white theme, then of course, "y0rk's White ADW theme".
In the very top row, you'll see the block-like apps drawer icons, including the neat one in the picture above.
Tap the one that you like, then back in the edit window, tap OK.
Congrats! You now have a sweet apps drawer icon. =>
You can also do this same procedure for any other icon on your home screens, whether they're in the dock bar like the apps drawer one, phone, etc, or whether they're just elsewhere on any home screen.
