[Sony Xperia T, TL, TX, V] Antiga Prime:
Given that I totally dislike most, if not all, stock apps/bloatware, I tend to disable (and eventually remove) the ones that I don't need and I'm sure can be disabled/removed and not affect the phone's usefulness.

I usually start with Titanium Backup in a gradual process, and between restarts, just to be sure, and then for subsequent flashes I do it with SManager. In case anyone is interested, I'm posting below the packages I disabled, along with the PM command used, and attaching the script files I use with SManager (ADB and/or terminal emulator can also be used to run the scripts), which you should copy to your phone.

Note: You need to gain Super User access before running these commands:

P.S.: I'm on [MENTION=4872623]DaRk-L0rD[/MENTION]'s deodexed version of EXR's Leaded JB 4.3 ROM, but I'm pretty sure most packages are the same in both ROMs (don't think [MENTION=4872623]DaRk-L0rD[/MENTION] removed anything).

And if you're really going to uninstall system apps, be totally sure and/or make backups first.
