Ok, now that we can see how much free RAM we have on our phones (Using SBSettings) how much free RAM are people seeing when their phone is just idling? I'm not just creating this thread because I'm bored, I do genuinely want to know, just trying to see the lowest peoples drops too and the highest peoples goes to.

Anyway, mine is currently sitting at 175mb RAM free, when I first Jailbroke and checked it, it was at around 370mb free

It change depending of the type of app a just open (and of course what App i got in the Background). most of the time I am at 80~ish.

Shouldn't be too worry about free RAM, Free RAM is wasted RAM and contrary to popular believe on idle mode a full RAM sucks as much power as empty one.

With it off I have 512MB free. But I used to get around 320 meg after just booting up the phone or freeing ram in sbsettings
