Change wifi country code

[woody1]

Does anybody know a good way to change the wifi country code? I was traveling in Europe recently, and I stayed in a hotel where all of the wifi channels were in European bands not used in the US. I'm looking for a way to change my US Mediapad to accept European wifi channels. I've seen some apk's around that are supposed to do this, but they're all pretty old. It should be possible to do it by modifying a system file.
