I have used iblank and gridlock but no matter what I do, when iconoclasm is at 5x5 it is impossible to get them to go where I want. I have never been more frustrated with anything on the iphone to date. I have seen so many GREAT themes and I can't use any of them because I cant arrange icons?! Someone needs to figure out a way to have these themes made with icons already where they need to be. I would pay double for themes if I didn't have to arrange the icons.
