The link in your post is the documentation about the Arnova 9 G2. The question from Rodders1969 is about the Arnova10 G2!?
By the way, i do have de same questions about the 8 G2, and i asked Cajl at http://www.jbmm.fr/2011/11/et-puis-cell ... nova-8-g2/
I looked through all specs and for the 8 G2, 9 G2 en 10 G2. For all models you can read in the chapter "Connected" the following info: "With the integrated microSD card reader you can transfer files easily or even plug in a USB flash drive in the USB host slot / via the USB host cable
So we have a HOST-function, the first step......
When you read the PDF-files (not available for the 10 G2) you will find out that only the 9 G2 has a 3G option: "3G Ready
The ARNOVA 9 G2 is fully compatible with the ARCHOS G9 3G Stick**. This USB Stick brings the
3G connectivity to your ARNOVA 9 G2 tablet via the USB port.
All you have to do is to put a data Sim card into the stick, plug it to your tablet and start surfing at
3G speed. Stay connected wherever you are!
I hope that owners of the 10,8 an 9 G2 models can test/confirm that the host function is supported so you can plug in a flash/hard drive or even a 3G stick.....
