Can't imagine why you would want to tether an EDGE phone anyways. The connection is dead slow. Acceptable for a phone, tedious at best tethered to a laptop.
Why is it that every time anyone has anything to say about the data connection on the iPhone we get the obligatory "EDGE sucks" joker response? A) I think we all get that EDGE is (supposedly) slower than 3G and B) I think we're sick of hearing it from the peanut gallery and C) it's not at all helpful or productive to snipe (grow up). Eye.Surgeon, I apologize for appearing to pick on you personally. I'm not. But you just happen to be the straw that broke the camel's back.
When I moved to the iPhone, I also switched my wife to AT&T and a Blackjack. And we just spent the last 2 weeks driving up & down the east coast on a family vacation. So let's just say that I have ready access to AT&T devices with EDGE and 3G and a lot of side-by-side comparison time (tethered and stand-alone).
I'll start off by saying this: if an iPhone existed with 3G would l I want it? Only if it also had EDGE. I have found 3G to be very spotty in its availability - like to the point of being a big surprise when it actually becomes available on the Blackjack. So before you go beat up Apple for not including it, you might want to first beat up AT&T to actually deploy it so it could be used. More important, I just don't see a big speed increase. Really. OK, if I was going to download a huge data file or stream hi-res video, maybe I might see a difference but we are talking about handheld devices with small screens meant to be mobile devices (not laptops).
So let me take the next logical leap... presto! we now have 3G. "OH MY GOD! CAN YOU BELIEVE APPLE INCLUDED SUCH A SMALL SCREEN ON THIS P.O.S. DEVICE?! WHAT A BUNCH OF IDIOTS!" or "ARE YOU KIDDING ME? WE GET 3G AND A GREAT SCREEN AND WE CAN ONLY STORE 4 OR 8 GB OF DATA ON THIS DEVICE? WHAT THE HELL WAS STEVE JOBS THINKING?"
The current iPhone is what it is. If there is a villain in the 3G moral outrage, then it's AT&T because their 3G network isn't out there for the majority of us. But there is no villain. The iPhone has been out for many weeks and for months before we all knew what it was and wasn't. I just think the iMoaners need to stop the silly sniping any time anyone asks about a data-related feature.
Back to the topic at hand, I too would love to see an easy tether app created so I could use my iPhone as a modem. Right now, I have to use my wife's Blackjack (oh, there's that EDGE vs. 3G real-world comparison thing again - after 2 weeks on the road, I can report that EDGE works just fine for tethering and it's a hell of a lot better than the alternative of no connection at all). But while I'm waiting for it, I'm going to go vent my moral outrage at Dell for not including 3G in my Latitude laptop. CAN YOU BELIEVE THAT?
