I was asked this question, or a similar question, when we launched the iPhone with Verizon. What I said then, and I still see it as being the case today, and I think you can see this in the products that have been shipped, is that the first generation of LTE chipsets force a lot of design compromises with the handset, and some of those we are just not willing to make.

And so we are extremely happy with the iPhone 4 and iPhone 3GS. Hitting 18.6 million units was something much larger than we thought we could do this quarter, and we're happy to have gotten it out to three more large carriers.

On the carrier side, I don't want to get into specifics about CDMA (or GSM for that matter). But we are constantly looking at where we should bring on incremental partners. As we said earlier, we brought on three large ones this quarter, with Verizon, STT and Saudi Telecom. That's on top of the ones that we brought on in December, where we added O2 and Vodafone in Germany. And so we are constantly looking and adding where it makes sense, and you can keep confidence that we'll continue to do that.
