The processes button Free Memory apparently has never done anything for anyone at all! I had one user report this and no one else. I found this today while installing SBSettings on a friends iPhone and noticing that there was no free memory after hitting the button. So none of you have ever seen how awesome this is! It is fixed now. Turns out I packaged the 3.0.1 toggle pack up poorly and the file was copied to the wrong folder.
v3.0.2 of the app changes the way the window opens slightly. It now requires at least 50 pixels of swiping before the window opens. This is to help prevent accidental opens. You can swipe left to right or right to left, it doesnt matter. You cannot swipe down. (Lets see if this one generates me any mail).
SBSettings can be downloaded from the BigBoss Cydia repository.
