i made custom boot logo's for iPhone and iPod Touch 4.

there is an image for 64, 32, 16, 8GB versions.

how do i have my boot logo select the correct image based on what hardware it's running on, without user input?

basically i want to have ONE cydia package with my boot logo, that will only install on iPhone 4 or iPod touch 4, and will show the correct image at boot time.

how can i do this?
