Template:T-Mobile WAP Settings
From HowardForums Wiki
Before manually configuring your handset it is recommended that you use the T-Mobile Settings Configurator as it is the best and easiest way to have the settings sent to your phone and it works for most phones regardless of branding.
This segment is also mirrored on the T-Mobile Data article.
