I got this email today, filled out the form and should be up to speed within 24 hours they said. The offer expires 5/10, but look for similar offers with different dates in your area. I'll play for 3 months and then cancel. I figure they'll be giving away the 6 Mbps service around then if Verizon rolls out their previously announced 6 Mbps DSL next month.
