Believe or not but the new iPhone 3G data plans by AT&T have not made customers happy so far.

Above all, now you will need to pay an extra $5 every month to get 200 text messages which usually came free with previous iPhone data plans. So below you can read a trick on how to send unlimited text messages from iPhone for free.

Here we will be making use of a famous email-to-text service called Teleflip.com

1. Create a new email message on your iPhone.
2. In the To: box type, 1234567890@teleflip.com (where the numbers are placeholders for any 10-digit phone number), type a message and send.
3. Enjoy free text messaging!

The message will be sent to the number in the email and all received text messages will be sent to you as an email.

If you want to use a web app to send text messages, use TxtDrop or Durgle as they work best on iPhone Safari.

Note: This trick will work for iPhone users in US and Canada only.
