hey, im about to jailbreak my ipod touch 2g mb and set my own custom custom boot logo: the file size is 74 kb and the limit is 100. when i try to open it with redsnow it says that it is invalid png, and that the compressed image is 143954 bytes but it need to be 102400 bytes or less. Try reducin its complexity. Dont understand why it says that. In photoshop the colour mode is RGB colour 8 bit, and the resolution 72 pixels/inch. And of course 320x480. I've saved for web and devices and select png 8. Can anyone help me please?
