Reports are starting to come in that users in the U.K. have already started receiving their S21 devices today, Tuesday, 26th January, some 3 days ahead of the official release date of Friday, 29th January.

These seem to be the carrier models from the carriers themselves, so far.

So, have you got yours yet?
