I want to get rid of my Hero since the EVO is coming soon. But its pretty obvious that unlike GSM phones I cant just pop the SIM and sell it. I need some help on how to sell my phone and stay on contract the same time... I want to sell it before release day for the EVO so it wouldnt be as simple as pushing over my number to the EVO.... SO how do I sell my phone and keep my contract going. help please??
