> Fair enough. In my country it is (I did not think that there was a country that did not charge for its data).I use a SIM with pre-paid on it which is nice (no contracts, nothing).

In the US it's common to require unlimited data packages for smartphones. The G1 and iPhone are examples of that. It's also common with BlackBerry. It's uncommon to pay by the megabyte here, you either don't have internet access or have unlimited (well, "unlimited") access.
