Here's a tip on how to send & receive unlimited SMS messages from your iPhone (assuming you have an unlimited data plan).
The steps are as follows:
1. Create a new email message.
2. In the "To: box", type firstname.lastname@example.org. (email@example.com)
3. Type a message then click send.
4. The message will be sent to the cell phone with the number in the "To: box"
5. All recieved text messages will be sent to you as an email.
