how come my free space keeps going down? like when i reboot i have about 180 mb or free space but 24 hours later it'll drop to 115mb? this happened on my 9300 as well, is it normal for blackberries ?
Yep... memory leak. Sometimes it is better or worse depening on the OS or apps you have. It varies from each device. Two users could have the same device, OS, apps with different results.
Back when 7.1 was released with .163, I had no memory leak. I also know of a few apps that gave me a bad severe memory leak.
