I uninstalled all the game trials, Vodafone Discover, Update, Qype, Talk. Even google maps I uninstalled as it's running in the background and only eating up battery.
Now everything is running well. I removed Twitter, Facebook, etc. I am with official B885 Vodafone ROM.
With Root Uninstaller which is free. Don't uninstall Online Upgrage then you won't be able to update your phone if new update comes. Make a back-up of the apk data in case they're needed. All of them will lbe backed-up to a folder called Root Uninstaller. You can then transfer it to your PC and then remove it from your phone.
@OP: Making a full unroot to the SuperSU thing will simply unroot your phone to get rid of the icon, as if you didn't root in the first place. Meaning you'll have to root the phone again if you fully unroot. Unrooting has nothing to do with deleting vodafone bloatware. In fact you won't be able to delete the vodafone bloatwares if you make a full unroot.
