Will iPhone 4 also benefit from HSDPA data speeds max out at 14Mb ???

I see no reason why not. Highly doubt there are any technical restrictions preventing current users from enjoying these increased speeds. Anyone think otherwise?
 
No, iPhone 4 customers won't see 14.4 Mb/s due to COMM chip limitations and design.

The GSM chip in the iPhone was designed up to 7.2 Mb/s down.
 
Ahh man, I didn't know that. Hopefully they AT&T can provide an average of 5-7mb's down...
 
the 4S has 2 antennas and uses kind of like a MIMO technology, (like in your wifi router) to give a faster speed, the 4 therefore can't be retro upgraded.
 
Don't worry. iPhone 4S will never see those speeds either. AT&T just does not have proper H+ equipment anywhere and I doubt that they are going to upgrade existing H+ infrastructure now that they started deploying LTE.

Are you sure about that? I think the hspa 14.4mbps is just a regular hspa design.

The only thing I've seen with the mention of dual antenna (MIMO) use is dual carrier hspa+ that starts at 22mbps and up. I think several networks have been updated in north america (and other countries i'm sure) that can do dual carrier 42mbps.

Where did you come up w/ this?

No, the 4S has a chipset that supports HSDPA 14.4. The chip in the 4 only supports HSDPA 7.2.

AT&T has HSPA+ and enhanced backhaul in place at many cell sites- most, if not all major urban and suburban areas. So yes, existing iPhone 4 owners will benefit from the upgrades, they just won't see speeds as fast as the 4S is capable of.

yes I was mistaken it doesn't use MIMO, but I do wonder where they get the extra point 4 from? as wikipedia says that it should just be 14Mbit/s dead :confused:

Hahaha, that's what you get for trusting Wikipedia. If you follow data measurment you'll realize it should say 14.4 Mbps.

Yeah, the 4 will max out at 7.2 Mbps....in optimal conditions.

But the iPhone 4/4S utilize HSDPA...:confused:....
 
sorry i dont have an iphone just a blackberry but am seriously considering getting the 4s, i just need to know one thing, it takes me about 4 minutes or less to download a file around 100mb, for what reason do you need to have a phone that supposedly utilizes 14mb download speeds? are there apps on the iphone that are gbs in size? or is everyone just impatient?..not to say that im not but just wanted to know app file sizes and the need for massiv download speeds.....

4S is upgraded to using HSDPA/HSUPA/HSPA+. 14.4MBPS.

I get 3-5mbps on my 4 in my area. That's plenty, broadband speed, on my handset. Thus one of the many reasons I'm not upgrading to 4S. But that's a personal decision.

As a friend of mine says... "I wouldn't trust Wikipedia to give me directions to my refrigerator!"

Seriously though, Wikipedia is wrong more often than you'd think.

They got it from the spec sheet of the Qualcomm MDM6600 chipset they implemented in the iPhone 4 CDMA and now the iPhone 4S.

It's wrong.

ATT has long deployed their 4G/HSPA+ network which the new iPhone 4S supports. As explicitly shown in keynote, there are several Android 4G phones already using this higher speed network.

Ahh.....That's good news. Thanks.
 
Pretty sure I read, that iPhone 4 won't get the 14.4 speeds but will still benefit with 7+ speeds.

Of course, they have been promising 7+ HSPA since the release of the 3GS.
 
its more of a gimmick, in order to get those speeds you need to be in areas that have a strong enough connection. However, most of these areas provide wifi funded by tv/ cable companies.
 
OK simplify it. If I am in an area where ATT's HSPA+ network (with enhanced backhaul) exists, what can I expect (both theoretically and actually) with a 3GS, a 4S, and a Samsung Galaxy S2?

Just rewatched the keynote, re-read a few articles, and checked again on Apple's website and they all specifically state it is HSDPA. No mention of HSPA+ at all. Makes sense too because if it was HSPA+ capable, it would support speeds up to 21mbps instead of 14mbps.

From Apple: http://www.apple.com/iphone/specs.html

UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz);
GSM/EDGE (850, 900, 1800, 1900 MHz)

You are wrong.

It uses the MDM6600 chipset, feel free to look up it's spec sheet.

So if I have an iPhone 4 now in Chicago and I get an average download speed of only 2.0 mbps on a theoretical max of 7.2 mbps, would an iPhone 4S make my 2.2 mbps actual speed faster just because it has a theoretical max of 14.4 mbps? Or is there a bottleneck that still would limit me to 2.0 mbps?
