reboot your phone and watch that number go higher. then watch it drop as you use apps. reboot and it comes back up.
try having a 8330 running 5.0. i don't have a lot of apps. but as of right now. i got 15 megs after reboot. it eventually drops to 5 megs. if i do a clean install. and nothing loaded or even service books. i get 36 megs to play with. good thing i don't use bb messenger, cuz that's a pretty big program that i just don't have room for anymore.
Your memory isnt low, plus you can improve it by taking out what you dont need like languages you dont use,sample video, etc etc... AND make sure all your media goes to the media card. But 116 mb is plenty of memory.

116 is rather high, if you are interested in higher memory, you jump over to the hybrid section and use shrinkaos with the hybrid 5.0, I believe I've seen someone shrink their OS to close to 50mb.
