I wonder if the re-sale values will hold once more people realize that the 3G only gets EDGE data speeds on T-Mobile, and once everyone starts dumping their 3gs onto the market within the next 12 months...
I think they will. The 3g adds GPS functionality and alot of 2g tmobile users want it.
Plus if someone losses thier phone and needs a new one paying $300 is nothing compared to full price.
