I have just updated to IOS 6 and am having nothing but problems. The update went fine, rebooted my iPad 3 and then the problems started. When I restart the iPad each time I am presented with the grey IOS 6 screen. I slide to login and I am then taken to a Wi-Fi page showing my Wi-Fi options. I tap the blue highlighted box 'Next' and am then presented with a pop up box to continue with or without Wi-Fi. I request to use Wi-Fi only for the pop up to keep appearing. I cannot proceed unless I tap 'Continue without Wi-Fi. Also there is no Siri in my general Settings, amongst a whole host of other issues. I am beginning to wish I had never upgraded. Certainly not a smooth road so far. I would like to revert to the older OS, at least that worked without having to jump through hoops each time I boot up. Please help somebody. Thanks.
