I replaced the SIM card with my own one. The 3G is working, I can ping from the command line.
The browser does not work, as the proxy config seem still be on.
As I own a Kindle 3, the /opt/amazon/ebook/config/browser_prefs does not exist.
Can someone provide me a tip how to make it work?
At least browsing would be fine....
(In my country I am not able to browse at all in 3G)
