The JB Update for Xperia T has been long awaited, and now it's here. It's a magnificent update with tons of new features and optimisations, however, I would like to bring some insight regarding a few problems I found out about to the Sony Support Staff :
1) The weather widget, which I loved and was the only weather app/widget I used due to it's sleek design and animation, now has a major flaw. Althoug it works properly, for some reason It creats a LOT of lag when put on a homescreen, while sliding across screens. The lag seems to have something to do with the animation, as it stops the second you start to slide and begins 1-2 secs after you stop sliding and look at the screen it's on. If you slide across screens, the one where the weather widget is on creates quite a huge lag, drops a lot of frames, whereas in the ICS version there was absolutely no lag, and no such problem. Seems to need a bit of optimisation! I'd love if Sony would become aware of it and work on it as soon as possible, because it's a shame to use a 3rd party app for weather when the native one is so beautiful and simple
2) Just like the weather widget, the Walkman widget also seems to cause lag, but significantly less than the aforementioned one. Again, the widget created no problem on the ICS version, so we're probably talking about some optimisation that needs to be done
3) For some reason, after updating to JB, the game NFS Most Wanted has been rendered incompatible with the Xperia T (according to Google Play), and thus can't be installed, which is annoying since it's a great game and everyone who has it payed 5-6 euros on it. I don't know if EA Games or Sony Mobile should adress the problem, but it needs a quick fix as it's aggravating, shince now we're talking about "locked" money and entertainment.
Hope this helps and gets to the ears of the Sony Mobile staff responsible for coding the software!
My update took ruffly 25-30mins... I thought it updated correctly but got an error installing the NFC part of the update... I then connected my mobile to the computer and repaired it using sony companion... My advice to you is do the same thing, update it by connecting it directly to the computer and going to the software update section... Hope this helps
My phone has stuck in the installation phase and its not starting, so i cant connect it to my laptop.
what happens when you connect it to your laptop does it recognise it at all?
nothing,,,the phone is not even starting.
the update was running on my phone then after everything finshed it restarted and then it turned off after the start up animation, and the cycle is still going, it turns on, animations comes and then it turns off again.
Hmmm sounds like a special case the only thing I can think of off the top of my head is let the battery run dead or try a soft reset... hope this can help mate.
So if your device is refusing to reboot the old fashioned way, try this option, the soft reset:
Tried this...as soon as it vibrated i released the keys.
I saw the SONY name coming
Then XPERIA name coming
Start up animation
and then again SONY name coming
This cycle is not stopping
Any suggestions please..!!!!:smileysad:
Sorry mate no idea
Try turning your phone off and flashing the update again via sus, to turn off press and hold volume up and the power button for about 10 seconds until you get 3 vibrations your phone should now turn off and then update again.
Hope it works 
It had turned off, but how do i update it again without turning it on.
It wont start!
After the startup animation it again restarts, and this keeps goin on.
