Delays in getting ICS on the Galaxy Note have some considering unofficial version.
If you are one of the reported millions who own the Galaxy Note 5.3 “phablet” from Samsung, you are still waiting for them to release Ice Cream Sandwich to run on your device. That is an on going problem for Samsung to deliver on what they have promised to do. When the device first was released, it was supposed to arrive with Android 4.0 installed, but did not. We expected to see it in March according to Samsung and have not. Samsung is now promising ICS for the Galaxy Note some time in this quarter which is vague and not very promising. We are seeing numerous reports of leaks for Android 4.0.3.
These are unofficial versions of Ice Cream Sandwich available and as a result, you are not going to get any support from AT&T if you purchased your Galaxy Note from them in the event that you run into problems. Installing these unofficial versions of Ice Cream Sandwich are not for the faint of heart. Many are reporting on methods to install such as Engadget though they are also reporting problems as well which are going to have to be fixed before the official version comes out. It definitely appears that this is a work in progress for Samsung to get things working correctly.
There are instructions in a number of places for the leaked ICS build for AT&T, such as the Android Community on how to perform the install of the leaked version of Android 4.0.3. RootzWiki appears to be the place to go if you want to install the unofficial version of ICS from AT&T and they are even providing the exact specifics on how to do this. Since this is not the official version of ICS from AT&T, there are still some things which are being worked on and not completely working as expected. As an example, the first time that you boot, the TouchWiz launcher crashes. There are other items on the list and one of note is that this leaked build does not come with the Premium Suite which has been promised by Samsung with the official release of Ice Cream Sandwich for the Galaxy Note.
