I am not saying to overuse the Internet at Amazon. And I appreciate the internet from them.

But if I'm not wrong in the EU is the law:

However, here (in this forum) is a tutorial on how to use another SIM card.

I have a cheap prepaid SIM, where the operator allows 3G telephony.

If the Kindle 3G already has a built-in 3G module, why not use it to make 3G call?
