I know people are waiting on the ICS upgrade, but I want to remind everyone of what Samsung says at the end of their ICS upgrade announcement:
"Get Ready for the new Galaxy Note experience made possible with Premium Suite. Available 2Q 2012. Features, functions, update schedules, download methods & etc. will be subject to changes depending on country or carrier."
I realize there are different opinions, but what I get out of this statement is that the ICS upgrade will be available (ready if you want it), 2Q 2012 (no later than June 30 2012). However, the features (what it will entail), functions (how it will work), update schedule (when it will be released), download methods & etc (over the air or via a computer), will be subject to changes (at the discretion of), depending on country or carrier (in my case USA & At&t).
With this opinion in mind I can only imagine it's less likely that Samsung and FCC are holding up the process, and more likely the folks at At&t.
