What does the red T stand for in the top right hand side of my Treo - I swear I can't find it in the book.

Also, I can't register for Bix Conn - says my user name and password are incorrect - what's up with that??

And while you're here - what's up with eamil?? I can get it from the computer Sprint site but not the phone - says it's not set up yet????

ANY HELP IS ALWAYS APPRECIATED!@!!
