I recently ordered an unlocked iPhone from the US. It has a software unlock although I do not know if its the free one or the iphonesimfree unlock yet.

My questions are:

Will iTunes notice I am using it in the UK and not let me update it? Does being in the UK in anyway change any iTunes settings?

If its unlocked with either software does that mean it has already been jailbreaked and I won't need to do that again?

I am sure I have more questions but they have slipped my mind for now - but anyone with a UK iPhone please let me know anything important you think I should know. thanks.:confused:
