I don't get your stressing over this. You will never use 16gb for apps unless you load insanely large games. I don't play games on my phone so this is not a concern for me.
Things that waste space such as music, pictures, videos, backups, roms, kernels and mods can easily be put on the sdcard.
I am just trying to keep my phone as clean as possible. My last phone which was just a LG optimus had nothing but trouble with trying to keep it worthy for internet use even, I know this phone is worlds away from where I came from, but just playing around with it for the last week, I managed to suck up 4 gigs of space on just setting up my phone and thought it would be so much easier to just transfer over to a sd card. The other thing is, I a currently using wicked sensation personal rom and 4.1.1 JB I will most likely be changing that to make updates and dont want to loose all my apps and stuff on the phone when I flash a new rom. Plus maybe I am missing something here but I cant seem to transfer anything over to my sd card. pics,backups. I don't know I probably just dont know how to do it even if its stairing me in the face.
What exactly are you trying to do that Is giving to trouble?
