If you want to pick up some easy-to-read info about 3G technology, 3G around Europe and Long Term Evolution (LTE) I recommend this blog by Martin Sauter. I’ve been following it for about a year now.
Martin also contributes to another good website, the Prepaid Wireless Internet Access wiki where people contantly update the latest pre-paid 3G offers around the world. A must-read if you’re ‘roaming.’
