"Unlimited" 5GB Data plan from Sprint

Here we go again. Following Verizon and AT&T, Sprint is the next U.S. carrier to offer 5GB of "unlimited" data plan.

Once the Terms of Service are modified on July 13, if you violate the 5GB limit or exceed 300MB of data while roaming, the company will have "the right to limit throughput speeds or amount of data transferred and to deny, terminate, modify, or suspend service".

What do you think of that?
