I don't think I'll be able to sell my DInc2 when I get an upgrade. I have never had a phone as great and reliable as this one. I'll be keeping it as a backup for a long time I think.
I just got rid of my old Nokia brick that I have had on a shelf for years "just in case".
If I do, I'll try this swappa-thing. Maybe That's where my Eris will go...
