Still can order from digi store? I have to go get it from SohoKL.. White owner here

They include 2 usb cable, 1 hdmi cable, 2 pin head charger, car charger and earphone... pretty complete!

first time user of this phone?
to save your frustration in dealing with the 3 capacitive buttons,
take not that the buttons are NOT at the transparent stripe.
it is also NOT exactly at the 3 dots too

it is actually ABOVE the 3 dots and BELOW the screen.
in other words, BETWEEN the 3 dots and the screen.

to ensure 100% strike on the buttons, do a swipe up motion from the dots to the screen.

this is a terrible design, and sony fixed it in the newer xperias.
i duno which xperia i saw in sony shop, i think its a cheaper but newer model, the capacitive buttons is at the transparent stripe, which is much much easier to hit.

anyway, its a great phone after you get used to the capacitive buttons.

use syncmypix, can download from google play, it works better for me, but u need to check after sync.

Up to you, I kinda happy with the stock, so I no root.

Just to remind you if you unlock the bootloader Sony will void your warranty.

u dont have to unlock bootloader to root & apply cybershot mod.
i've just claimed warranty for my rooted phone a couple of month ago

what do you mean must root your tab cos no update.
rooting alone wont increase your android version. its still the same phone just that it can use some root apps only.

rooting is not necessary, but for me i prefer to have root access.
mainly can use root apps, most important one is droid wall,titanium backup and rom toolbox.

can have a firewall deny apps to go online. example stop angry birds to go online so it wont waste battery and data to download useless adds. most games dont need internet anyway.
then using rom toolbox can disable adds all together, and prevent useless app from starting during boot.
titanium backup can freeze and delete useless system apps (bloatwares, apps that you dont use)

stopping apps from download adds can save alot battery life. some may argue this is unethical but i dont really care, battery life>all.

depend on many factors.

you on gps wifi 3G all the time? on only when use, turn off when not using.
main battery drainer is screen brightness, download a brightness widget and put in your homescreen.
adjust as low as you can without feeling uncomfortable.

i think can get 3-4 hours of screen on time.

With data on is normal, try juice defender.
