If you are running Gingerbread Stock firmware XXJVK on your Samsung Galaxy S i9000 and are desperate to see the Overscroll Glow effect on your device, XDA forum member dhiru1602 has successfully ported the functions and code required to XXJVK!
Note that a few Touchwiz apps that have ‘Swipe to Message or Call Feature’ will have the default scrolling and this mod does not take effect for such Scroll Lists since this feature is a part of Touchwiz and not Stock Android.
Additionally some Touchwiz applications use calls to inbuilt scrolling functions, hence it is important to preserve the old functions so that scrolling in a few Touchwiz apps works fine. The XDA member has ported these new Scrolling functions from the Nexus S ROM.
To install, head on over to the modification thread to download the zip and flash with ClockWorkMod. (Only compatible with CMW3)._________
