Hey, I think I might have to fix my T39m. Did you ever figure out what they were talking about?

better leave this job to a trained person or u might just end up killing your phone.....dont do it unless you are 100% sure what you are doing..

i think most of this t39 problem is in the rf proc same as the T2x series, looks like u guys have to change it instead of just rehot it
