I hate to say it, but since jailbreaking I've started paying much more attention to how much free memory my phone has. With a fresh respring it is around 250-300MB, but usually hovers around 100-150MB, and easily can drop to <50MB with some greedy apps (e.g. Zite newsreader). Usually closing all but a few essential apps (Music, Notepad, 2Do) only brings me back up to 150MB. Sometimes even that doesn't work, and I'm left stuck below 100MB... So, I'm trying to figure out what is using my memory. There seems to be dozens of "system" apps out there that are all clones of each other, but none have the ability to show how much memory each APP or PROCESS is using. All they show is priority. One exception was "MemTool", but this app hasn't been updated in years and no longer runs. http://www.appleiphoneschool.com/2009/03/02/memtool-view-memory-and-process-info/ Are there any tools out there, native or jailbreak, which give REAL information on what is using memory?
