Hello MarK...
I too have been clamoring over the configuration info....I have a 7100t (T-Mobile)...I do not have BES, Im relying on wap.
After going through this several times, I finally changed the port #from 1290 (as stated earlier in Configs, to 9201...
and it WORKED ! YEA ! Finally !!
wap.voicestream.com-----TCP-------TOC Host & Port------change numbers to 9201..
when I initially downloaded the program, the number listed was 1290...
Hope this helps !!
