I gave up on the facebook app a long time ago. Look for the "Facebook lite" apk. It doesn't hog the memory like the original. You will have to download it to your sd card and change a setting to allow software from "unknown sources" in your phone to allow it to be installed. Wow, I just looked, found it in the play store now. Looks like a more up to date version, but it claims it's not compatible with my phone.
