After many hours of fiddling with my modded Arduino-TNC and my HTX-212, I finally got it to transmit a test email from my cell phone using WoAD.

While trying to troubleshoot my Winlink packet connections with my home-brewed, slightly modified Arduino-TNC, I found that mobilinkd has made a GUI tool in python that allows you to adjust the settings. The only problem was following the instructions to install it!
