The PocketSurfer works everywhere your cell-phone works.  DataWind's solution is network agnostic, and will work on past, current and future networks, providing the broadest coverage of any handheld web device.  While other products are limited to next-generation 2.5G and 3G networks, with limited coverage -- the DataWind Web Viewer will deliver a faster, richer experience on 2G networks, than most devices can on even 3G networks.
