A question...

My SG3 is Vodafone branded and unlocked (SIM Unlocked). I've been thinking of flashing my firmware with a Jellybean official stock ROM to remove the Vodafone branding... as well as eliminating the bloatware.

I don't really mind losing the Vodafone warranty, but will I still be able to get updates from Samsung through OTA or Kies if they send updates for the stock ROM I'll flash my mobile phone with?
