I dont know if this has been asked before.
I want to know if its possible to remove specific, unwanted system (/system/app) APKs from the update.zip (such as FRF84BV04.zip), so that when its installed, it will only install what is in the zip file. I never use CPT, original maps.apk, Gmail.apk, and a few others. It would shrink the zip file a little, and give me less hassle when installing, so I dont have to uninstall these files manually after I install the zip.
Can I just pull them out of the zip file, without resigning it?
