64x64 Is what I use. Icon converter will convert any jpeg, bmp, etc. to a 64x64 ico file. Then copy the progams exe that you want to change the icon for to your desktop. start Reshacker, go to file then open. select the exe you copied to the desktop. Once open go to action and select replace icon. Point the popup browser to the icon that you made. Then ok then save. Then overwrite the original exe on the phone with the one from the desktop and you're done (you may need to soft reset for the icon change to show up in TF3D.
