Here is some info about UMTS/HSPA bands:
UMTS/HSPA Bands (W-CDMA)
- Band I (2100 mhz) in Europe, Africa, Asia, Oceania (ITU Region 1) and Brazil (part of ITU Region 2)
- Band II (1900 mhz) in North America and South America (ITU Region 2)
- Band IV (1700 mhz) in the United States (T-Mobile USA)
- Band V (850 mhz) in America, Canada, Australia, parts of South America, parts of Asia (ITU Region 2 and ITU Region 3)
- Band VI (800mhz) Some parts of rural Japan on NTT DoCoMo
- Band VIII (900 mhz) in Europe, Asia, Oceania (ITU Region 1 and ITU Region 3)
- Band XII - XIV future use in the 700MHz spectrum
So, it appears 900mhz isn't supported? Do you guys think that there is a second iPhone? Or that none of the stated providers are on 900mhz networks? Also, people who thought they were going to buy an iPhone and use it on Tmobile's new 3G network are in for a sad surprise with 1700mhz band on the iPhone 3G.
I don't think 800Mhz is used much anymore in Japan, so no big deal.
Does any of this mean that the iPhone will be supported on the Verizon network?
No, Verizon and Sprint use CDMA2000 networks (which is popular in N/S America, and some carriers in Japan/Korea) whereas AT&T (and most of Europe/Middle East/Africa) uses GSM/UMTS networks. It's an entirely different technology unfortunately. The good news is that AT&T and Verizon are now on the same upgrade path for LTE/4G for the future...
So no HSUPA on this chip, despite the fact that AT&T has been actively rolling it out across the USA? Or am I missing something here? HSDPA is all well and good, but the upload speeds are pretty weak compared to HSUPA...
Yep, that sucks the big one. Not only does HSUPA increase upload speeds from 150-200kbps to 500-900kbps, but it vastly reduces latency on the uplink. That's probably the biggest advantage. HSUPA chipsets are just now being rolled out in cellphones. Probably didn't make the cut in the design phase. Of course, I always expect Apple to lag on technical features, but usually that is on their computers. Oh well, 384 UMTS will have to tied everyone over until iPhone v3. I wonder if this will have an effect on Apple's decision about including video conferencing or not. I doubt it will be able to use Wifi, unless we are talking about a chat app that doesn't use the cellphone voice network. Although the likely 150-300kbps upload may be ok for low res video conferencing.

In this phone's hardware I expect 3G at 7.5Mb/s down, GPS with a fix in as little as a second...
Woah, hold it right there. Even if AT&T's HSDPA is rated to 7.2mbps, you'll be lucky to peak at 1.0-1.5mbps, *especially* on a phone versus a broadband laptop card. And initial GPS fix in a second? What utopian world do you live in?
Maybe it just needs better programmed safari.
Perhaps that Squirrelfish thing for javascript and a load more optimisations. I'd rather see them go that route than the traditional method with desktops of throwing more and more power in to make up for the bloat.. Flash player used to clog things up on my /dual G5/ lol. People just need to get back to programming properly. :/ (not that i'm saying that's easy or realistic)
Yes, I hope to see the new Webkit get integrated into an iPhone Safari update. Should speed it up! Not to mention someone needs to find out how to turn up the CPU clock on the iPhone. It's a factory 620mhz chip, but it's underclocked to 400mhz I believe.
So does that mean the new 3G iPhone will work in Asia also? It would be awesome if I can use it in Japan.
Yes, I believe Softbank already announced they are getting the new iPhone. I'm pretty sure they are on Band I (2100mhz).
What makes you say that? Or am I missing something? Every 3G phone available here seems to have video conferencing (NEVER used).
The whole "front camera on every 3G phone" thing is prevalent throughout most of the world, with the glaring exception of the US. See, the vast majority of people in the US buy their phones from carriers, and all the carriers have the manufacturers make phones for the their market without the forward camera. Why? I have no idea. It's seems like it would be a great way to nickel and dime their customers to death.
