Political wouldn't make much sense anyways as you'd expect any Kindle not to work. As you say I reckon it's got to do with the telco partnering. Be interested to see how the DXG goes. I had full web access in country where ever I tried it and it certainly helped fill in the time sitting in cars, buses and trains

I didn't even think to have a look and see what network was being used because I wasn't aware of the US Kindle "deadspot".
The 3g has easily paid for itself in a couple of overseas holidays.
We bought 5 prepaid Vinaphone sims for voice and SMS and they worked a treat during the 3 weeks, and MUCH cheaper than international roaming.
