Will give this a shot and report back. If I remember correctly though someone on another forum tried a 3rd party app and got the same result, due to the fact that it is a 'security feature' to prevent spammers from mass texting people. Google would probably figure spammers would attempt to circumvent the security by doing this.
But we shall see!
