Apple has zero incentive to offer a single phone that could be used on either network. The reason is simple. They can sell an unhappy AT&T or Verizon customer another phone if they make them separate whereas the ability to simply reprogram the phone would cost them a sale and Apple is all about GREED baby.

Your hatred of Apple is noted. Why you are here is a mystery however.

Are you Kidding??? They have enormous incentive to have a single device. The reduction in expense of their manufacturing alone would be worth WAY more to Apple than the occasional extra handset sale. Let alone the reduced complexity in supply-chain management. Finally, from a user-perception perspective, having a single iPhone that is not directly associated with either AT&T or Verizon would reduce user perceptions that network issues were the fault of the phone.
 
Does this chip support the 1700 MHz AWS band?

Qualcomm MDM6600 combines all the core technologies of the third generation, existing in the world. MDM6600 supports frequency ranges from 450MHz to 2100MGts, supports GSM / GPRS / EDGE, CDMA,HSDPA,HSPA (up to 14.4 Mbps) and EV-DO (to 14.7 Mbps) as well as the technology of satellite positioning GPS and GLONASS, which is especially important for the Russian Federation.

A quieter vibration motor? Seriously? I can barely feel it now. I have a silicon case and can't even hear it vibrate on a table. I have friends with blackberry's and I can hear it vibrate in their pocket from across the room.
 
I highly doubt its a technical issue.

What I suspect it to be is a product segmentation issue.

1. Apple needs a reason to sell you a brand new iPhone 5 in June. The Verizon iPhone 4 is really only a suitable upgrade if you're coming from a "dumb" phone. If you have a smartphone with internet/mail now its a good idea to wait.

2. Apple didn't want to release a Verizon iPhone that, if you put an AT&T SIM card in it, outperformed the AT&T iPhone 4. The chip in the current AT&T iPhone only does 7.2Mbps, the new chip does 14.4Mbps. AT&T is said to be in the process of upgrading their network (both the towers and the backhaul) to support HSPA+ speeds and is supposed to announce some sort of plan by the end of March about how its going to be upgraded.

3. Licensing issues. If (I don't know this for sure) Apple doesn't have to pay a fee to GSM licensing/patent firms if the GSM features aren't active in the phone, its more money in their pocket. What I suspect is that if the iPhone 5 is built around this chip, we still might see separate GSM/CDMA phones because Apple doesn't want to pay for both radio technology licenses for every phone they sell. If its $10 for GSM and $10 for CDMA, then thats $10 more in costs per phone if they use both technologies.
 
Oh Ok I think I misread....they didn't include a separate GSM chip in there, they used a Qualcomm chip that is dual band sort of all-in-one in the single chip.....people speculated that they couldn't do a world phone this time because they wanted to rush a CDMA iPhone ASAP! But this kinda debunks that...this phone is already a world phone! So why not enable it? They either just didn't want to, and prefer having two models or did Apple figure that if this iPhone 4 had the dual functionality enabled that it would be considered something other than an iPhone 4? I don't get it....

Verizon's other wold phones block the US bands so you don't take you phone to at&t or T-Mobile. They could have done the same for now and allow international use. So I doubt it was Verizon's call....
 
Wandering if their is already enough internal space to slide a sim card and try into the ViPhone? May be a clue that the 5 is already designed in a familiar package.
 
gotta guess iphone 5 will do "4g" (3g) hspa+ with this revelation. doubt we'll see an 4g lte iphone til 2012. pretty sure ip4 doesn't support hspa+ but supports hspa
Here in Canada I'm running my iPhone 4 on an HSPA+ network, but it's guess the network itself is backwards-compatible to HSPA speeds.
 
I can already barely feel the vibration! When I'm up and walking around I can't feel it at all and now they're making it less powerful so that its not as 'jarring' when its on a table... wtf? it's supposed to alert you!

Completely agree. I've been waiting for Apple to improve the vibration on the iPhone, since the iPhone 3G. It is hardly noticeable, and for text messages it only does one wimpy vibrate. Wish there was customizable vibration with different intervals, etc.
 
Wait a minute? So the Verizon iPhone is indeed dual mode, it has a GSM radio on it...but Apple chose to simply leave it inside and...do nothing with it?

What's the point?

Once again, Verizon cripples a phone. Verizon doesn't want you to give you options.

That's correct; you can use an HSPA device on an HSPA+ network but will be limited to HSPA speeds (7.2 Mb/s, if I recall correctly).
 
iFixit tweet:

"RT @Lessien If I'm reading page 14 http://bit.ly/hwkjlX correctly, the MDM6600 (which is in VZW iPhone 4) does support T-Mobile 1700Mhz."

Indeed, it seems that it does support 1700 mhz as long as it is coded for in the software. Screenshot of the manual for those interested.

iPhone 4 is already HSPA capable (7.2mbs). AT&T just finished rolling out HSPA+ (14.4mbs)....but we will have to wait and see if iPhone 5 can support HSPA+.

If you are using Verizon's CDMA, average user throughput is around 1 MBs. :(

You win, a thousand internets to you fine sir.

Manufacturing one device for as many technologies as possible will give you economies of scale, along with the power that comes with negotiating with suppliers - you buy more, you get more power and more say.

Product conversion costs also plummet. That is, you don't have seperate lines for this iPhone and that iPhone and this other one.

You'll also have less testing issues, which is a significant issue.

I suspect that the economies involved more than make up for the increased price of the chip.
 
GSM is kinda on the way out as well, since LTE isn't backwards compatible with it. CDMA and GSM will be around for at least another 10 years.

Qualcomm has a chip also as a chip called the 9600 which does everything the 6600 does but add LTE.


Wait a minute? So the Verizon iPhone is indeed dual mode, it has a GSM radio on it...but Apple chose to simply leave it inside and...do nothing with it?

What's the point?

Using the 6600 now helps Apple in volume pricing when the next iphone comes along just as
 
Would a dual mode phone allow consumers to switch carriers at will. If so, what does that do to subsidizing and plan pricing?

I doubt it. AT&T will likely still lock the GSM/WCDMA side, and I believe that Verizon (and certainly Sprint) will not allow devices from other operators on their networks.

+1000000

This has been one of the most annoying aspects of the iPhone from the very first generation - along with the weak speakerphone/ringer volume.

I have always been jealous of my friends who are able to both hear AND feel their phone ringing in their pockets, or in other rooms, or *gasp* in public. I have just learned to look at it every few minutes to see if I have a missed call that I didn't hear/feel. The price I pay for the other awesome features :)

I like it weak. It doesn't work in a jacket pocket but it works fine in a pants pocket. It's supposed to be quiet - I've never understood why it's impolite to have phones ring in a board room, but ok to have them make an extremely loud buzzsaw noise instead. Everyone knows your phone is ringing either way.
