Update: Looks like Samsung has now announced that the ICS release is not coming out tomorrow!
We have already seen leaked builds of Google Android ICS available for the Galaxy S II smartphone.
Samsung has now officially announced that they would launch this update tomorrow.
Customers who want to install it immediately would be able to do so manually using the KIES software.
Samsung would also deliver the update over the air but that could take weeks for some users.
This release is expected for the international unlocked edition. Variants of this model sold in some markets like the USA are likely to get updates in the future because of customizations.
