Yep, find the image you want to use then use ninjamorph. Start new project, and find the image the click on it, then find the new image on your SD card, click it then hit yes. Once you change all the images you want go back and hit finish project. it will ask you several questions answer yes to all but the zipalign question. It will then restart. it may take awhile to find what you want to change, and there may be several images for a single notification, ex. I changed my 3g icon to 4g and that was 4 different images; data in, data out, data in/out, and no data. Each image needs to be renamed exactly like the file its replacing or it won't work.
