Give it a rest dude!
It IS often I do EXACTLY this sort of thing, so I speak from experience.
I've done it with the N95-3, N85-1, Sony Ericsson XPERIA X1i, and now with the iPhone 3G. With the exception of the N95-3 (I held onto it for a year), I sold the other phones to at least break even with exactly what I paid for them (I got good deals on the phones, though, so that helped with not losing too much). You got the phone for $500, which is $100 of the next best price.. it's not going to dip to that price for a while. You could EASILY sell it for the price you paid for it, if not more, if you treat it with care while you own it. The N97 could easily be the next phone I sell away to at least break even, and transition to another phone.
If you paid $770, fine, fair enough, I would see your complaints. But at $500 I honestly can't see why you're complaining so much. You're acting like it's a $500 no-name phone that no one is going to buy used. That's NOT the case, and it's NOT the end of the world.
