FreeContact add the capability to send any contacts from your address book via email.
After selecting a contact, you can choose which details you want to send; for example, you can choose to send only the cell phone number, or to include also the associated photo, email address, physical address, note, etc.
Before sending the email, you'll be prompted to choose between a simple plain text email containing the selected infos, or an email with a vCard attachment.
The application is fast and easy to use: the selection of each contact's detail, including the photo, can be made by simply tapping over it.
In the settings pref panel, you can also set-up the default behaviour, e.g select all details.
