I apologize if this has been answered somewhere else, but I've searched high and low and haven't found any definitive answers.

I have a theme I've been working on where the icons are actually 140 x 165 square (iPhone 4 res). I love the way it looks and for the most part it's been working fine using the old method (icons folder/naming the image exactly how it shows on the screen).

Well...I'm running into some apps that the method won't work for such as Star Wars Battle for Hoth (has a colon in the display name that I can't put into the file name) or Angry Birds/Angry Birds Halloween (they both use the Angry Birds display name).

So...I've tried starting to convert to the new method with Folders/xxxxx.app but I can't get the icons to go larger than 114px no matter what I do.

Any ideas?
