This is a very sad sight to my eyes

Not even basic Root yet
Phone has been out for 2+ months and ZERO development for ATT users
Nothing but tumble weeds blowing, and crickets chirping.
F u ATT.
Thank God I have my OnePlus One, this phone is a beast, especially running CM12 already. But would be open and tempted to go to the Note 4 is I could root it, and install ROM's. But I am on ATT, which does have excellent service in my area, and a very good plan = $130 / Month for 2 phones = Unlimited minutes + Unlimited texts + 10GB Data, and rock solid stable network for me.
I'll pass on paying $700+ off contract for the Note 4. On ATT would be like $99 on my plan, but with no root = no way.
