For me too, those generations are moving fast, so it's better to have a WWAN-free device to keep up with a cheap phone which handles it. They're cheap especially in combination with a contract.
For me it's a bug to call the iPhone an "internet communications device" introduced in 2007 without 3G.
But for use with phone you need the bluetooth, right? And what about the bluetooth bug restriction in our N800?
Many cell phone data plans specifically exclude tethering. Some allow tethering. The plans that allow tethering tend to be more expensive than those that don't. I'm implying that in order to run that speed test, I had to tether on a non-tethering plan. Of course I'd never do that, right?
When the iPhone goes 3G, real flash implementation, DUN, can interface with a Blackberry server (which I have heard rumors of), all hell is going to break loose.
