Thanks you all.

I assume by data it means not only email, but basic web browsing etc.

When using these "data" services and not using it in 3G, but rather GSM, is it possible to use Skype or related applications?

Also, related to WIFI, what is people's experience on finding free service. I don't have a device that is WIFI enabled, so malybe I'm missing out on the possibilities under the impression that most of the time it requires subscription.
