I recently stumbled across this plist Google it, if you want to download it. com.apple.dynamic_pager.plist "This daemon will enable your iPhone to harness the power of your iPhone's flash storage to extend the capabilities of your RAM. I have noticed through usage of this modification that applications open much faster, and backgrounded applications rarely ever quit themselves. I can run 7 applications simultaneously and have 40 MB of free RAM. Keep in mind--this daemon causes very frequent writing to your flash storage, therefore reducing its life." I was wondering though, if this works for iOS4? Or if there is an updated version for it... I don't know much about it, but my iPhone 3G is dead slow... i'd enjoy a boost.
