I am running firmware 1.02.20 and the automatic updater does not pick up anything newer, however, looking at 'Things Every …....Should Know' I see the latest version is 1.03.12; but reading through each version there appears to be negatives for many of them. We are 100% happy with our T2 so although I like to keep up to date on techie things software wise is there any advantage in me upgrading from 1.02.20? I am also running custom firmware 2.12 -same question. Wife will not be pleased if I mess up the tele!
