TF3D 2.5 is by far the best version of Manila to date, with all its shiny new features comes a new way to save your information. Favorite peoples tab has over gone some changes that gives it a more TF2D look, but it is still good and shows you more information and allows you to have more contact.
The new peoples tab takes some time to setup when you start out. That is now going to change, because if you are a person like me, you flash about 2-3 times a week and that means starting over again.
Not anymore. If you have activesync/device center or even Myphone service, then you can sync your file and that means your favorite contacts will sync too. Then when you are done with the flashing your device, just restore you file and that will restore most of your things in TF3D 2.5.
