i got the htc hero just a few days ago and started a 2 year contract with sprint. i wanted the evo but it was just a bit out of my price range at the moment and i couldn't stand being with att any longer. Radio shack announced that it is giving away free phones on father's day regardless of the plan you choose. i know i have 30 days to CANCEL my service but is there any way to turn in my hero for an evo?!?!?! please help me out!
