Sprint has just launched a new service that employs text-to-speech technology for allowing customers to send text messages to any landline. Called, cleverly, "Text to Landline," the service is compatible with any SMS-capable phone, and allows the receiving party to respond with either a voice message or canned text selectable from their phone's keypad. We sent a message from our PPC-6700 to our landline, and the service worked exactly as advertised, reading the text in a pleasant female voice (one we were already familiar with from Sprint's voice-controlled customer service menus). Even better, sending these types of texts costs no more than a regular SMS, so you can feel free to harass your friends with humorous/vulgar spoken messages on the cheap.
