Looks like ESPN isn't the only company who won't be texting Sprint customers anymore.
Details are scarce, but as of today, Weather.com is suspending service to all Sprint/Nextel users.
We are no longer able to offer SMS messages on the Sprint/Nextel network and will suspend service on 4/12. For more mobile products and apps, go to weather.com
Pretty sure it has to do with the same fee structure ESPN decided not to deal with. Shame, really, but them's the breaks.
