How to know free memory on var
ok I used a CFW with 1000mb partion, so how do I know how much free space is left on it? cuz I have SBSettings but not sure I'm reading it right. It says
HDD Free:605 MB on/184 MB on /var
Available Memory: 19 MB
So how much is free on var? cuz I know iTunes says I have 19 MB free.

There seems to be a lot of confusion as it relates to Memory and Storage. Let me see if I can explain this:
RAM: Memory = brain.
HDD: Storage = your stomach.
They're independent of each other.
The 3G iPhone has 128MB available RAM (memory), and - on an 8GB device - approximately 7.1GB available (the rest is used by the iPhone's operating system).
Of that 7.1GB HDD, you can store applications, music, photos, etc. Once it's full - you have to start emptying it.
Of the 128MB RAM, processes/applications require brainpower to work. And when you combine multiple processes and applications all running at the same time, it decreases the amount of brainpower available to run more processes/apps. If too much is used, the iPhone experiences crashes.
Although just an assumption (I only have user experience to validate), I have found there are certain apps and processes that cause memory leaks - decreasing the total amount of memory available for use. Respringing or rebooting the phone will reset the memory levels. As will some 3rd party apps.
Hope this helps.

RAM (memory) - 19MB
HDD (storage) - 184MB - available for apps, photos, music, videos, etc.
Another way to check it, launch Cydia, choose Manage, and then choose Storage. It will give you -on a pie chart, a breakdown between the System (your 1000 partition), and Private (var) drives.
