How much free RAM on iPad without any apps running?

[pjny]

Hi,

I upgraded from ios 3.2 to 4.2.1 and noticed I have anywhere from 100-120mb of available RAM without any apps running. I'm just wondering if this is unusual or that the iOS takes up 130-150mb of RAM just to operate.

I have a few tweaks like SBSettings(no Winterboard) that are probably taking up RAM. I just wanted to know what the baseline is without any of these tweaks.

...without any apps running.

Phone, Safari, Mail, and iPod are always running in the background. Because of their grandfathered nature its possible they don't adhere to the same multitasking conventions that Apple allows for 3rd party apps.
