Galaxy S GT-I9000 appears to have been officially sidelined by Samsung since its release. The smartphone shipped with Android 2.1 Eclair at launch, and was later upgraded to Android 2.3 Gingerbread. But there has been no further software updates from the Korean smartphone giant, and I9000 users have had to depend on custom ROM developers for regular Android updates.

Owing to the release of the latest C-RoM Mix custom ROM, Galaxy S GT-I9000 users can now enjoy the latest Android 4.1.2 Jelly Bean update on their older smartphones. With credit due to XDA Developers member aways, the new C-RoM Mix ROM blends the features of two of the best custom ROMs, CyanogenMod 10 and AOKP Jelly Bean, from the Android market.
