This build thus far rocks....it feels stable enough that I'm updating my S3....
Its still downloading....it will take awhile I'm sureI just got my 2gb/64gb today. Let me know or start a new thread of how it goes. I am planning on putting it on tomorrow.
I even gained an extra gigabyte of HD space, and that's including having a Windows.old folder from the future.
So far none and I was getting tons on 10147...any wifi drops after sleep or hibernate?
