I have an 8320 through T-Mobile running v4.5.0.81. Per the suggestions on the last few pages, I've resent the service books several times and have also deleted and recreated the email setup through BIS. HTML mail and images are both enabled, and the APN is set to wap.voicestream.com.

When trying to view HTML mail, I get just the HTML code in text form (all the style sheet code and such). Suggestions?
