At&t note 2 update overseas? Possible?

[nvarras7]

I have a note 2 that I bought in tha States and now live in Europe. At&t wont let me get the update here. I'm wondering how I can get the update, anybody know? I've never rooted a phone and have no clue, would rather not try something new as I am a new dad and don't have much extra time or money for a new phone in case I brick it.

Do I actually have to be on the AT&T network or will a sim do the trick? Any Ideas????
