I'm not surprised to hear its a custom chip. I really hadn't heard anyone else say it was definitely A15 and so I was still kind of skeptical. I'm also kind of skeptical of a SGX543MP4. That just seems like too much space to waste and totally unneeded for the iPhone. I like the compormise of a MP3 with higher clocks.
Can't wait to see this thing's X-ray.
What am I wondering about is the noise cancellation circuitry. Apple used Audience in the 4 and 4S and they've already come forward and said they're not in the 5. I'm wondering if Apple is handling it all in software now. As for the Siri aspect, I would presume embedding a microphone in the earpiece would solve the "hold the phone at arms length" issue.
All in all, I still can't wait for this thing to arrive. Putting my GNex on Craigslist tomorrow so that I can hopefully get it out of here by Friday.
Edit: What I'm not excited for is keeping AT&T. I won't get LTE in my hometown for another couple of years AT LEAST, but HSPA+ isn't bad here. Looking forward to those LTE speeds in Charlotte though. Had thought long and hard about switching to Sprint, but the simultaneous voice/data thing killed it for me.
It went so much that I want to talk and surf at the same time, but id really like for my data connection to not be interrupted by a phone call I'm likely not going to answer.
