Looks like we’ve got the first Ice Cream Sandwich ROM for Galaxy S II (I9100). The XXKP1 build as we can see in the video runs Android 4.0.1 and comes with Samsung’s TouchWiz UI with some ICS-centric features. Calling, internet and messaging seem to work fine but some apps crash due to apparent incompatibility.

SamMobile who got hold of the build claims that the ROM is a “Custom Samsung” build and shouldn’t be tried by first-time flashers or users who flash stock ROMs.
