Dear App friends,
A new version of SMS-Fast is about to arrive in the App Store. The new version is called v1.1. It enables you to select exactly which number and email address to use for a contact.
You now select a contact and see that contact's full data sheet with name phone numbers and email addresses. You press a phone number and an email address and then press the Done button. That's it and you get full control, as it should have been in v1.0.
