How can I forward a SMS text message?
For iPhones using firmware 3.0 or higher, forwarding of SMS messages is a built in feature. To forward a text message, simply
1) view the SMS text message conversation containing the message you'd like to forward
2) tap EDIT at the top of the screen
3) check off the message(s) you'd like to forward
4) tap FORWARD at the bottom right of the screen
For those using older firmware, there is a third-party application for the iPhone, iSMS (or weiSMS), with which it is possible to send text messages to multiple individuals as well as forward text messages. Find out more here.
