I am with AT&T also. I have a Galaxy Note currently running 4.0.4 .....I check for updates and a message appears that says I have the latest and that no updates are available. I have been told by my husband that AT&T just hasn't released the updates. I do not understand it all, but it would be nice to be using the latest version...if it is available. ???? does anyone have any info on this issue? thx
