Question [Q] OTA Updates and International Travel

Just curious, I was noticing on one of the "Update" threads that someone had a A500 bought in the US but was living in NZ, and he recently got the OTA .42 update - my question is directed to anyone who has traveled with their A500 internationally - has your device received a local OTA, then OTA when you got home?

As I'm off to Perth in about a week I'm wondering if I should be turning off auto updates (or at least rejecting any AUS update I get while in country)? Will there be any functionality issues (GPS maybe?) if you take your US A500 into a different country and stay on your US update?
