i won a brand new BB 8120 in that contest. I recived my phone in hopes of having a nice toy to hold me over till the bold. I used to have an 8700g that still works but is all scrtached and such. Anywas the problem is the memory i did the optimizing and all and i got 20 mb but slowly it goes away and i have nothing running and nothing i went to play basket ball with out using it an dleft it in the car and it went from 18.1 mb to about 16.7 mb randomly, i had only 1 missed call and 1 text, mind you have barley anything on it and a media card. what can be causing this
