said by Warzau:Anyone have a "Backgrounder" alt, I used to use it and loved how it shut down app automatically and left one I wanted. Doesn't seem to work in new iOS. I know the developer stopped working on it long ago. It worked up to 5.1.1. Also does Bite SMS work with 6.1. I use it all the time on my 3GS and 5.0.1 iOS. Hate to update and realize one of the most use app doesn't work.
Really have not seen much need for backgrounder - I used to use it and in IOS6 - they do a pretty good job of process control. Just look at the running process and free memory (in sbsettings)
