Yeah, a straight up swap probably isn't gonna work. But since i dont think my worn out mogul would really get that much $ on ebay, i'd take the $30 sprint would give me for it on a trade for the diamond. I read on another thread some dude already called up sprint, and asked them how much they would give him for his mogul as a swap for the diamond. 30 measly dollars
But, its an option, if true. i'd do it.
