Are you in a situation where you want to share updates quickly via text message and you don't want to take your eyes off the road. Try this trick for your iPhone to send pre-written text messages with the help of Airplane Mode.
This is from the amazing http://lifehacker.com/ web-site!
Lifehacker reader Drew Sikora shares a clever technique for tricking your iPhone into staggering pre-written text messages. The trick relies on the method the iPhone uses for handling errors while text messaging. First put your phone in Airplane Mode and then write all the text messages you wish to compose ahead of time—like travel updates. When you attempt to send them they will error out. This creates a queue of unsent messages. When you turn Airplane Mode off, they don't automatically send, they just sit there waiting for some action from you. Now when you are traveling you can easily send text messages—like "I'm just cross the California border into Oregon" by simply tapping the message to attempt a resend.
Check out the full article at for a detailed run down of the technique including how to use it to update social networks as well as notify people via text. If you're sporting an Android phone you may be curious if this trick works with Android. Alas, it doesn't—Android sends all text messages automatically once you turn Airplane Mode off—but you could use Google Voice Actions to dictate your text messages to your phone while on the road.
