So you just bought a Galaxy Note 10.1 for yourself and want to know how to make the most out of that amazing tablet? Samsung Mobile has posted several useful videos that do a wonderful job of explaining the utility of S-pen in Note 10.1.
The above playlist contains 15 videos. Make sure to watch them all.

Cyanogen Mod 9 is nearly complete and is working like a charm on the ATT i717 Galaxy Note. It is a great firmware for those who want pure Android experience without any touchwiz or any sort of addons baked. Heck, the developers have not even included an S-pen app. They suggest you to install Papyrus and Markers app from Marketplace if you want them.
I received this question via email today from a Samsung Galaxy Note 10.1 (Galaxy Note 800) user:
Here are all the modems for the ATT Samsung Galaxy Note i717. If you are on ICS, you can use any of the following modems. To flash them, boot into CWM recovery and flash this zip.
