unless my information is wrong... on the 3g touch you can only browse wikipedia and the amazon store when you are connected through 3g, when you connect through wifi you can go everywhere.
This is true. . . .
The reason is that Amazon is paying for the 3G. I mean, they called it "free" but that meant free to YOU -- not free to THEM! They still had to pay ATT for the bandwidth!

My theory is that they locked it down because, while they wanted people to have access to THEIR site they didn't feel like they should be subsidizing all of a person's browsing.
Which I can't really argue with.

Sure it's convenient in an emergency, but most people nowadays who have a need for a browser on the go, probably have some other device available that works better -- even if they do have to pay for it themselves.

I always found the Kindle browser frustratingly slow -- more like slogging through the wet sand on the shore of the internet than surfing it.
