From Homestar Runner Wiki
Wireless Bizness was an abandoned project created by The Brothers Chaps to have Strong Bad Emails on mobile phones supporting WAP. At the time it was accessible, the few emails that were in it were all plain text with short emails having short answers. One of them was later given animation and featured on the TV Time Toons Menu. E-mail Birds are reportedly based on another three WAP emails. It is not known why this project was terminated.
 Likely WAP Emails
