Will 4G wireless be an option on the S? 3G speed seems slugish

There actually is no such thing as 4G currently.

LTE is the 3.5G technology. Unfortunately one provider started calling LTE 4G for marketing reasons, and everyone else ended up following suit.

Actually, I thought LTE (Long Term Evolution) WAS the 4G technology and carriers like AT&T were boosting speeds on older technology and then calling it 4G?

I'm betting AT&T since its likely easier to have the hardware a bit agnostic (use SIM cards) than to put in a radio that's specific to one carrier. Audi uses T-Mobile. Do any cars use sprint or verizon? (though its likely Sprint would be the cheapest)

Verizon also uses sim cards for it's LTE service. I bet it will be Verizon, since verizon just announced an initiative to have it's 4g lte service put into automobiles just recently

What I am hoping is that Tesla Model S will just accept a usb dongle or pci slot so that you can swap out to which ever provider is best in your area, or for whatever reason a better service comes along in 5 years.

That is correct. With iOS update 5.1 my iPhone 4S changed the 3G badging to 4G without a hardware change. It was At&t calling HSPA+ calling itself 4G even though it is really 3.5G. At&t is calling it 4G because they offer similar speeds to the current incarnation of 4G LTE. Of course 4G LTE is supposed to evolve to higher speeds.

So, calling it "4G" may be a Trojan horse. I look forward to hearing the final verdict.

HSDPA+ is branded as "4G" by both T-Mobile USA and ATT.

ATT and Verizon are offering "4G LTE" also which uses a roadmap towards 4G speeds, but it currently does not meet 3GPP 4G specifiications.

HSPA+ is really 3.5G
LTE is 3.75G at the current moment.

Well, to nitpick, even "4G LTE" (as touted by Verizon and ATT) is not the true LTE (as defined by the standards committee)!

The current "4G LTE" out there: 4G - Wikipedia, the free encyclopedia

The true LTE ("LTE Advanced"): 4G - Wikipedia, the free encyclopedia

My understanding is that, while Verizon uses SIM card for its LTE network, their LTE phones still use the older CDMA interface for 3G and voice. LTE is great, but it's still not available everywhere and for a vehicle that's supposed to allow for travel between urban areas that seems short sighted.

My bet is on AT&T because it uses one GSM sim for all connections (if I remember correctly). Also, this will allow them to transition to the worldwide market better as the rest of the world uses GSM.

At the Annual Stockholder's Meeting a few days ago, Elon mentioned "every car has 4G."

ya, we're trying to figure out "who" now
