In the course of owning this phone over six months, I've done a fair amount of hacking and tweaking, thanks almost entirely to the devs and other helpful members here. But after a version upgrade and trying out a couple of custom ROMs, I've accumulated quite a few installation files. Do I need to keep them? For example, if I have a custom recovery, I assume I need to keep the .img file, but can I get rid of the .rar? With .apk files generally, can I just throw those away after installing from them?
