i have this recurring problem in my n73. after some time, it'll say that my phone memory is low and that i'll have to delete some data. when i check the memory stat, free memory is only around 9mb (i dont have anything on phone memory except contacts). when i check the breakdown, it only adds up to about 10mb (used memory). where did the other 23mb go?!!
i hard formatted my phone. and it works fine for a few days. but messes up again after a while.
