It clearly seems that the WiFi issue is the big reason for the iOS 4.2 delay. The new GM has been released only for the iPad, and it seems that Apple solved the WiFi issue. So, if you had the issue on your iPad, has the 4.2 GM 2 solved it? For me, it seems that it has been solved.. But I want to be sure, before voting. So I'll wait and test it for some hours.
