Apple has been testing the iOS 5.1 software update with developers for several months now, with the most recent seed, beta version three (3), being seeded in early January. While it does appear that development of iOS 5.1 has slowed down for the time being, BGR claims to have gotten their hands on the "Gold Master" build of the update. A Gold Master (a.k.a. "GM") build of software is usually the final, shipping build of an update.

From the GM build, BGR says that Siri will be gaining Japanese language support, which has been rumored for the past couple of weeks now and previously promised by Apple. In addition, it appears as though access to the Camera from the lock screen of iOS will be available by sliding up on the new icon. The icon will reportedly be "persistent," meaning that it will always be there. In the current version of iOS 5, the Camera icon is accessible by double-clicking the home button.

iOS 5.1 is expected to be released on or around March 9, 2012, the rumored announcement date of the next-generation iPad.
