9900 still has memory leak problem?

i found out that my 9900 ( .296 ) still has memory leak problem... i installed an app about 2 MB, and after that my mem show 77 MB left. then i decided that i dont really need it so i delete the apps and it ask me to restart, so i did a battery pull, and after that my mem shows 120 MB free, i was kinda surprised (but happy though..), i thought 9900 free from this case...
