Folks, do remember that updates are released by regions and provider.
Just because one TX gets an update, does not mean all TX's will get it at the same time. It has to be released to regions and operators first. If you have a branded phone, you will still have wait (Maybe upto a month) as your carrier puts their bloatware on it. This is obviously a Sony release...just wait, non branded phones will filter through over the next few days, branded phones over the next few weeks
If anyone does not want to wait, just download the ftf and lfash it in flashtool (Once it has been uploaded)
