If you are located in the United-States there is a new iPhone application that allows you to send SMS messages for free while you get ads shown to you on the application. The application name is: textPlus. http://textplus.gogii.com/ I'm not from the US so i couldn't really check it but i found some good feedback about it. I hope to sniff it during the weekend so i could post some more information about how they are sending the SMS and maybe we could use some web service to send the SMS's instead of using the application. Thanks, kod.
