Hey all. Been using an iPad for the past 2 years, Upgrading to the new 12.9 but I cant seem to get it! I am upgrading via Vodafone UK and its not been in stock since release! O2 and EE are in the same boat. And when looking about online I can see that the WiFi only version is mostly available the 4G+WiFi is out of stock just about everywhere! Is there a supply issue with these versions?? Anyone heard anything?
