Maybe I should have waited

If I am to believe the rumours, the 3G iPhone is due out in Australia this year. I would really want a 3G iPhone. Faster mobile internet, proper headphone jack, fixed GPS. How could I not want one? It’s rumoured they will be sold UNLOCKED! It’s also rumoured that it will be significantly cheaper, possibly around the US$200 mark. I’m worried that if this turns out to be true my 2G iPhone will devalue significantly (eep!). This makes me want to sell it now, before the rest of Australia realises about the new iPhone. I could live without it for a few months, but don’t want to ditch it just on a couple of rumours. Should I have faith in the tendency of Apple products to retain their value, or should I accept the loss as an inevitable consequence of buying the latest gadgets that I don’t really need?
