Here is a link for the stock gingerbread OTA, system build 2.11.605.3, but it is rooted and debloated. For everyone who wants to stay stock but have root and no bloat, this rom is for you. Yes, you need to register with the forum to download, but team bamf does great work so its worth it.
Need help flashing the ROM? Check out This video.
Here is the radio that came with this OTA. The MR3 1.48.00.0906w_1 radio. Thanks go to Andrynalyn for the radio link.
