Sprint is doing a bit of spring cleaning, and that means the Picture Mail service is shutting down. Sprint has indicated via its web site that it will cease offering its Picture Mail web site on April 30. Sprint recommends that customers log in and download their stored media before April 30, as all their content will become inaccessible after that time. Sprint did not offer a reason for discontinuing the service. Sprint's Picture Mail service can still be used to send pictures, but customers will no longer be able to store them and access them online. With the dozens of options out there for sharing images these days, this move makes a lot of sense for Sprint.
