I just got an N9 on ebay. Everything's fine except using the default browser with the mobile data connection.

The default browser works fine with a WiFi connection.

Firefox, e-mail or the Nokia Store work fine with the mobile data connection. Everything seems to be working fine with the mobile data connection except the default browser. That's very weird, I know.

Any idea why this might be happening?

If I search for updates the phone says it's updated (Software version: PR1.3 (40.2012.21-3_PR_006)

Thanks for any help.
