MS already released the 8107 update for Gold!
Hours ago I flashed this ROM again. To my surprise, WITHOUT deploying the xap, only through ZUNE, the phone got two consecutive updates, 7740 first, and then, you see updated straight to 8107.
Of course by this way the official update replaced my Hspl with a factory spl, a 5.11 spl, which is very difficult to get back to HSPL at the moment. So if you want to keep the HSPL, follow ansar's instruction.
At first the connection setup refused to use my number. Then in the marketplace I updated Connection Setup to v1.14, and manually set the apn, user name and password. Everything seems going fine until now.
