Some weeks ago, we talked about sending MMS on iPhone. I still can’t understand it. But, moreovere, SMS sending is not an easy task on iPhone.
The SMS application lacks some useful features we had got used to. For example, sending the message to several receivers or forwarding existing messages.
Now we have found a better unofficial SMS application, provided by the community.
Of course, the installation is via Installer.app, that has become a de facto standard for installing unofficial applications on iPhone.
