Comcast says that they're opening up their Xfinity Wi-Fi hotspots to everyone to help first responders and victims of Hurricane Sandy. According to a press release sent to our inbox and a statement by Comcast in our forums, as of yesterday customers within range of Comcast's hotspots in markets affected by Sandy (PA, NJ, DE, MD, DC, VA, WV, MA, NH and ME) can now access those hotspots free of charge. "Non-XFINITY Internet customers should search for the “xfinitywifi” network name and click on the “Not a Comcast subscriber?” link at the bottom of the Sign In page -- Then select the “Complimentary Trial Session” option from the drop down list. Users will be able to renew their complimentary sessions every 2 hours through Wednesday November 7th." You can find a coverage map of all of Comcast's hotspots here.
