New day, new tweak in Cydia: iPhoneVM.This tweak is useful especially to iPhone 3G owners and the purpose is to free RAM memory by creating a swap file that contains all the processes that are not always used by your iPhone.
By holding the less important jobs in this swap and you’ll get better performance in terms of speed. You can find iPhoneVM in Cydia. Just add this repo: http://repo.beyouriphone.com. After you install iPhoneVM, reboot your iPhone.
NOTE: lots of goodies in the repo
In case you are wondering how well this is working, i used to have max 41 MB of free RAM. Now i got between 70 and 78 MB of free RAM.
