Details, please...
How is it faster/smoother?
Has the battery life changed? Did it get better or worse?
The rest of us are still waiting for ICS to be released in our regions!
Thanks!
Like xmr405o, I am in the US, but downloaded the UK region rom and installed it myself. I used the mobile version of Odin since I am more comfortable/familiar with it; though the regular version of Odin is probably a safer bet for those who can't wait, and want to upgrade themselves.
As far as smoother, everything seems to go easier, more fluid. I sense no more hesitation when I start apps, or transitions between screens, scrolling is even and steady. Also, I have limited experience with it but the video playback seems much improved in that limited experience since the upgrade.
Even my game apps seem to run more fluidly, menus come up more quickly, it's like it had previously been holding back.
The closest thing I have seen in comparison is that honeycomb reminds me of when a database is running low on tablespace, so it goes into garbage collection mode every time you try to write to the table, which causes small lags in every operation. Then later you add more tablespace (expand it , add another file, etc) ; , that reminds me of ICS, that lag that was taxing every operation is gone, and everything goes smoothly. That is really what it reminds me of the most.
