I am kind of curious to find out how that DN3 rom is working for you ....have you worked out all the bugs with the modem? I have done a little research on DN3 rom and looks very impressive.....but I couldn't find too many end user comments about how it is working or not. I too am having trouble with the Bluetooth range and would like to get it fixed....it doesn't look like I will get help from Samsung because it's an international note 2 where customer support is in Africa......I am in California
