The original SpeedMod kernel, now available for AT&T Captivate users! This kernel aims to be fast, compatible, stable, and have good battery life. It makes our Galaxy S run the way it should.
This kernel is for the AT&T Captivate (SGH-i897)
The forum thread for the GT-I9000 version is here: http://xdaforums.com/showthread.php?t=822756
WARNING: Before you try any lagfix, make sure that you have enough free space on your Internal SD. You should have at least more free space than data+dbdata+cache combined.
Latest K13E (12-Apr) - Voodoo Sound v7. Lowmemorykiller fixes. Improved display sharpness using AMOLED processing mode in MDNIE. Support for voice calls through headphones. Check here for more info and downloads.
Thanks to sasovics and rpicaso for the I897 boot logo!

FOR BEGINNERS:
This kernel is based on sztupy's Universal Lagfix: Lagfix and root options are accessible by booting into the Recovery Menu.
To get the best speed, it is recommended that you enable all Tweaks from the Recovery Menu. Tweaks are under SpeedMod features. Info on Tweaks: http://xdaforums.com/showthread.php?t=813309
How to root: http://xdaforums.com/showpost.php?p=8896862&postcount=90
Kernel HZ value: HZ=500 is smoother, HZ=256 is Samsung default.
