LT29i new owner reporting in.

upgraded to JB, looks nice and neat.

improvement on camera settings. i like the superior auto settings, auto-detect every scene for your camera.
and switching rear camera to front camera in just one touch. and yeah, HDR

wifi connected very fast, unlike on ICS, where i had to tap on wifi menu just to see it gets connected.

currently using stock rom, bootloader still no unlock yet.

not yet tested Sony UI launcher for JB, as i prefer with Nova Launcher.
and the keyboard pretty much same as Sony's ICS keyboard.
i have JB keyboard apps for that.

battery wise, it doesnt seem to improve greatly but hey, its a phone. not a notebook. you dont browse internet 24hrs with it, do you ?
but if you go to Settings > Apps > Running, you can see Overheat Control. thats very good.

im satisfied this JB update
recommend all owner to update it

so, how to update? because I cant update from pc companion and the flashtool said that my phone is locked.

aik. you sure meh ?
you using stock rom ?
mine just bought last week, i didnt root whatsoever.
just disable apps that i dont need.

hoho. cant wait for JB eh ?

maybe in your cached processes

i just install papago gps. but it does not fit the screen. it become small. i already change the organic file with 720x1280 and 1280x720 file. but it not work. anyone can help me????

After upgraded to JB, I found out this so far :
Cons:
1. Rotating screen is a bit noticeable lag. not as smooth as ICS.
2. When you have opened Opera Mini browser and leave the website opened, then switch to use other apps, then go back to use the opera has become black blank screen. Have to go to the Open apps list and remove it from list, then i only can open the opera browser back.
3. Phone dialpad, message and contacts background has become white.
4. Change theme already but sometimes still display old theme, and the wallpaper when lock screen still the old wallpaper.
5. Browsing websites is not as smooth and a bit lag at times.

Mine's ori set, not AP 
Haha 'B' version. That's good. By the way what's the first apps u guys install? My first app is Avast Mobile Security
