I had emailed Samsung a few days ago inquiring as to when they would be releasing the source code for the Verizon Galaxy Note 2 JB and I got an email today with info and a link. The details are below and when you get to the page simply put in SCH-I605 into the search bar and you will get the link. Not sure if or how much this will help developers but I wanted to post it.

Dear Customer,

We are pleased to provide you the source code of SCH-I605(JB). You can download the source code from the site below:

Thank you.

Sincerely yours,
Samsung
