PassAlong enables you to send contact information from your address book via text message and e-mail.
Sharing contact information using built-in iPhone functionality is limited to sending the entire vCard. With PassAlong, you can select whichever bits of information you like from as many people as you like and then send it all at once.
The selected contact info can be inserted into an SMS message, e-mail or copied to the clipboard as plain text for easy use with Google Voice or the Twitter client of your choice.
