I am trying to tether my blackberry curve 8530. I used the tether app from tether.com, but i do not want to pay the $30 fee. I did some research and blackberry desktop manager will allow tethering. During setup it has a drop down menu with different carriers to select, cricket is not listed. I added cricket, now it wants to know the settings. Username________, password_________, access point__________, additional commands__________. Does anyone use this for tethering? Or any suggestions to the settings?
