Probably not. The only OS for iPhone currently in beta is iOS 6. There are is no iOS 5.1.2 currently in beta and iOS 6 should be out within a few weeks. Unless a security hole in the current iPhone OS is found before 6 is released, don't expect an update to iOS 5.
No it did not. It had IOS 6. But you can get IOS 7 on it. Also when IOS 7 came out they put it on the iPod 5 in stores.

iOS 6 came out of beta September 21, 2012 with the launch of the iPhone 5. You can update to the latest iOS 6.1.3 (6.1.4 with the iPhone 5) by going into Settings>General>Software Update or plugging your device into an iTunes authorized computer if you are running anything older than iOS 5. If you are not fond of the iOS 7 update, then you must update to iOS 6 before this fall because after that, Apple forces you to only update to the latest software version or not at all. But you don't have to worry about this is you have a 4th gen iPod Touch or iPhone 3GS which can't get iOS 7.
You have to update your iPad 2 to iOS 5 if you bought it prior to the launch of iOS 5. You can update now to iOS 6 (and soon iOS 7), by plugging your iPad 2 into the computer you authorized with your iTunes account and waiting for the pop up that will ask if you want to install the new software update. The process should take 1-2 hours.
