There’s a little program out there called txtForward that will send all of your text messages that your phone receives to an email address that you determine.
Why would you want this? The same reason you’d want to use a service like Simulsays or Spinvox to have your voicemails converted to text and emailed to you – the email inbox, for many, is the center of communication. Also, having your text messages emailed to you means that you always have a backup. There is a trial available, otherwise it’s selling for about $10. Thanks to Jason Langridge for the source.
