I got 1 HTC Hero and 1 Samsung Instinct s30 in my Sprint account, 7 days ago I lost my Hero and I filed the insurance claim so I received my Hero replacement already programmed with my phone number. The point is that yesterday I found my original Hero so now I am wondering if I could replace the Samsung one for either the new or the original Hero. Can Sprint program my two Heros on my two lines even if one of them was a replacement?
