I recently bought a Kindle with 3G + WiFi. The user must register as being from a specific country. When you register as "New Zealand" your 3G connectivity is limited to Wikipedia and Amazon. If you register in Australia your 3G web connectivity is not limited -- you can get Google, hotmail, and any other website you want. I have tested this by registering alternately in different countries. Has anyone else discovered this?  How did it come about?
