I have an iPad with 3G and one with WiFi only. They are both of the same generation. I just downloaded and installed IOS 6 on each of them. Siri showed up on the 3G iPad but not on the WiFi only iPad.
I did them both almost simultaneously, the 3G was started a minute or two before the WiFi but the WiFi finished a few minutes before the 3G, like there was a bit more to download and install (Siri?) on the 3G. Is this the way is it is supposed to be or did I do something wrong or incomplete with the download?
