At a time when manufacturers are busy fitting their smartphone and tablets with Android 4.1 (Jelly Bean) and older devices are content with upgrading to Android 4.0 (Ice Cream Sandwich (ICS)), the Galaxy S 4G, strangely, has a Jelly Bean ROM update, besides porting the older ICS ROM.

Thanks to developer erikmm, the ICS ROM - Slim ICS - a trimmed down version of the original file with only select features and customisation options - turns out to be something users looking for an old-school ICS experience will actually enjoy.

Key Points

The ICS ROM update has a couple of issues - the ClockWorkMod (CWM) recovery tool can't backup/restore and UMS or USB Mass Storage mode is unsupported on this ROM

The ROM and the instructions in the guide are applicable to Samsung Galaxy S 4G - T959V model only and will not work with any other devices. You can verify your phone's model number in Settings > About phone.

IBTimes UK advises readers to back-up important personal data (bookmarks, contacts, SMS and APN settings). This procedure will the device clean

Here is a step-by-step guide to installing the Slim Ice Cream Sandwich ROM on the Galaxy S 4G
