A new custom CyanogenMod 7.2 ROM tailor-made for the Samsung Galaxy Ace GT-S5830 is already out, featuring the same theme and features of the Galaxy S3′s famous TouchWiz 5 interface and launcher.

The ROM is known as the CM7.2 SIII MOD ROM and it features the same icon pack, wallpapers, home launcher, and a few widgets that were originally found on the Galaxy S3. Although the ROM is not actually based on Android 4.0 Ice Cream Sandwich, it does, however, feel like you are actually running Ice Cream Sandwich on your Galaxy Ace. Keep in mind, the ROM is built on Android 2.3.7 Gingerbread which translates to a very stable ROM and is good for daily use.
