Getting new software on older phones is always cause for joy. Usually, the big prize is reserved for getting a whole new version of Android—such as Ice Cream Sandwich. However, sometimes little mods from new software can be fun as well. XDA Forum Member PaWill has successfully ported the TouchWiz 4 launcher for Samsung Galaxy S I9000 users who are running select iterations of Android 4.0 Ice Cream Sandwich.
The mod is installed relatively easily thanks to a recovery-flashable update.zip. There may be bugs, so if you happen to find any, please report them so they fixed. The current change log states:
Repaired scrolling wallpaper.
SGS CM9 Build 16
SGS Onecosmic 4.2
Nexus S AOKP b27
So if you’re running any of those ICS builds, then the update.zip should work properly for you. However, it could potentially work for almost any ICS ROM. As usual, be sure to make a backup before flashing just in case anything goes wrong.
