I asked BlueVia / Telefonica about the deliver date of the new Telefonica-Arduino-GSM shield again. Announcement / purchase see:
https://bluevia.com/en/page/tech.arduino
The really friendly support told me they had some problems with the launch and the release date got delayed. If everything goes as expected, the new release day is the 22nd October. I assume 2012, the year was not specified explicit.
