Hi , i have a Nokia 920 on Tesco mobile which is o2 and have been patiently waiting for the 8.1 update ,but i checked on nokias site and the update sais it should be available for Nokia 920 on o2 i have checked for the update manually and nothing is there .so i was wondering if i have to wait longer since i am Tesco mobile or if i should be able to get the update and its just not working ?
