When I had 5.1.1 on my 4S I used to have 290-300+ MB of freem RAM after closing all my apps and if I went to SBSettings and freed memory I could reach 350 to 358MB.

Now on iOS6.1 I can hardly top to 320 after doing that and my normal RAM consumption after closing all my apps is 250MB or lower. Im not sure if its any of the tweaks I installed but I guess not, they are light weight tweaks so far, being SBSettings the major one.

I have read recently that many people are moving from SBS into NCSettings and now that I ultra tweaked Activator I might not need SBS afterall but the info shown as "storage and memory available" are hard to get away with

Hows yours?
