Obviously, Samsung missed the target. Galaxy SII users in Europe and some other regions started to receive ICS update about two weeks ago. Nothing for Galaxy Note users.
Last week, Samsung officially pushed the date to Q2. So, your waiting time should vary from one week to one week plus 3 months. Usually, when a phone manufacturer tells in Q2, it usually means June; it seldom means April.
The good news is that Samsung will bundle the S-Pen “Premium Suite” Apps together with your delicious ICS. You may watch the preview video of this “Premium Suite” on Youtube. It is not so bad, anyway.
