Tablet [Q] GT-N100 - Stock Firmware Selection

Hello.

I own a Samsung GT-N7100 (Rooted, Running CyanogenMod 11)
I am thinking to download and flash the stock firmware (kitkat 4.4.2)
The initial problem is that i bought the phone from Greece and now i live in Glasgow.
There is a firmware uploaded for UK/Vodafone but i have giffgaff provider
Should i wait for an open UK firmware or could i just install the UK/Vodafone?

Thanks.!
