i called tmobile becuase i am getting a call failed/radio path unavailable problem
they fixed it for about three minutes now i am still getting it.
but i have a icon on the top right with a box with +'s in it.
has that always been there, and does anybody know what it is thanks

That's the "Bass Boost" Call Audio Enhancement Symbol

awesome, thanks man. must have just accidentally flipped it on

How do you enable it btw?

its in your general settings of the phone options

push menu button on the call log screen, select options then general options
