Like many have already said the earliest we will see a new iPhone is probably June/July(if the current trend continues) so it just depends how much you care about speed. My friend still has an original and every time i play with his i cant believe "how slow" it feels compared to the 3G. But it all depends... with rumors of an iPhone HD floating around maybe it would be best to wait 6 or 7 months.
You may want to consider how strong the 3G signal is in your area as well- if its strong you will be surfin' much faster.
But if signal is weak youll just be using the same old edge network the original uses....
it just depends
