Does iPhone 4S have 4G network capability? Confused...

    I thought mine didn't, but now I see "4G" displayed at the top of the screen when I activate Cellular Data. But without cellular data turned on, the screen no longer displays 3G like it did previously, it just reads AT&T.

    I usually don't pay much attention to these notifications, I wonder if this started with the iOS 5.1 update I just did?

    It doesn't have LTE.

    AT&T's "fake" 4G is HSPA+ which is 3G with enhanced backhaul.

    iPhone 4S does not have an LTE chipset.

    AT&T begged apple to change the icon when you are connected to 3G that is HSDPA+ because it does reach speeds close to 4G LTE. The 4G term gets used pretty loosely these days...

    Thank you, and also oakfit & RobertF64. I didn't think my 4S had true 4G. My husband's iPhone 4, also running iOS 5.1, continues to display 3G. But 3G no longer appears on my 4S, as it did formerly, it's now either 4G or nothing, if I have Cellular Data set to OFF. That answers my question. icon_biggrin.gif

    LTE as currently implemented is also "fake" 4G.

    Spooky, technically you are correct, however Verizon, AT&T and others pleaded with the defining organizations and had them revise what the definition of 4G is. This means that LTE is now 4G according to the revised definitions.

    OK, so my iPhone 4S doesn't have real 4G, which is what I thought before the 4G indicator suddenly began appearing on my screen.

    But what DO I have on this phone? Is it essentially as fast as 4G? I presume better than the 3G I had before? I hope I'm not being charged more, I'll have to watch my billing. I usually keep Cellular Data turned off anyway, which kills the pseudo-4G, as I rarely do much with my smartphone. Ordinarily I wait for a Wi-Fi hotspot, unless I need directions or info in the car.

    Whats the point in owning the device then? You can get a free or cheaper device if all you want is a phone. Confused.

    But I don't just want a phone. It's my calendar, my address book, notebook, email, text messages, photo album (8000+ pics), I use it to shop, check the weather, it even contains listings & reviews for 30,000 movies (I'm a movie fanatic).

    I've had nearly the same capability since the 1990s, when I began a 10-year association with Palm PDAs. But they didn't include a cell phone, and when they finally did it wasn't a very good solution. By then the iPhone was introduced, and after waiting a couple of years to gauge its viability, I made the switch.

    And I still use the cellular connection as needed, I just don't use it 24/7. Saves battery life and money.

    What he said. Keep in mind only AT&T customers are having this 'problem'

    Wireless subscribers abuse everything they touch. Have to move the data mess out of the voice bands.

    There was GSM(2g), UMTS(3g), so they had to come up with a new name for LTE.

    it really should say H+ not 4g. My blackberry has the same thing.

    The iPhone 4S supports HSPA+ which is a slightly faster 3G. Unfortunately for marketing purposes a bunch of manufacturers used the term '4G' to refer to their HSPA+ capable handsets. AT&T seems to have label HSPA+ as '4G' as well(who would have thought!). Thanks to that the term '4G' seems to have very little meaning and what should have been 4G today now is called 4G LTE or just LTE. Long story short that 4G icon is near the same as 3G. Let me know when u see 'LTE' right next to the AT&T logo.

    OK, so it's a marketing semantics game. I can understand that. And this alleged "4G" is a slight improvement over my 3G, but not too much. Thanks, this helps me to figure out what's going on.

    Progress is being made, judging by the teardown of the New iPad3. http://www.ifixit.com/Teardown/iPad-3-4G-Teardown/8277/3

    Top picture: The cell network processor is still separate from the Apple A5 processor (baseband). The top picture on this page is the radio circuits, stuff I'm more familiar with. The RTR8600 chip is very similar to the RTR8605 used on the iPhone 4S (orange box.) Two things kept the 4S from LTE: The MDM9600 baseband and an LTE-ready transmit amp (most likely the Skyworks chip.)

    (gulp.) The A5 has its own memory in the New iPad. But, they had to add another Toshiba flash/dram memory chip for the Qualcomm MDM9600. They didn't have this for the 4S and the MDM6100. That must have been a fun circuit board to design. icon_eek.gif

    TheGuyNextDoor saidIt's interesting to sit outside and give both the iPhone 4s and the new iPad a speed test to see how 3G+ and 4G LTE compete for download speeds.
    My RJ page is a bear to load.. but on the new iPad,, it pops all the photos up really fast in comparison to 3G+.. same goes for YouTubes that can lag.
    I now see what all that 4G fuss was about. It's just faster... Period!

    And.. I Like it!


    You seem to be the kind of guy that should take some things really slowly, and not be fast about it at allicon_wink.gificon_razz.gif

    I'd take that as a given. Apple really can't fail to have true 4G, since the carriers are installing the system. Spotty in some places, but it's inevitable.

    What are you using now? I offered you an iPhone 3GS when you had some cell phone gap, to get you established with a smartphone. Not leading edge, but not a basic flip-phone, either.

    So where are you now, and your plans for a phone?

    I still have my first responder's last generation i-phone (if I didn't thank you then....thanks so very much for your kind offer!) that I used for a couple of months at the end of last year; but I went back to my 2003 samsung propel phone when AT&T's extra $25.00 a month i-phone surcharge irritated me too much.

    I do miss the i-phone's superior camera, though.

    The i-phone 4's voice activated text messaging and camera viewfinder built into the front screen is tempting me constantly, as is sprint's one price "everything" cell phone plan, as 98% of my cell phone usage is texting and/or pictures, and I have found out from a couple of "close calls" that I cannot talk/text while driving. I actually perfer the raised buttons on my propel for texting, rather than the no-feel i-phone screen and exasperating auto-correct, but the limited range of the propel's texting at one time capability is sometimes irritating.

    I think that I will hold out for the i-phone 5 and once again engage in the eternal battle between my budget and my desires.

    I think only the 4S has voice dictation with Siri. I didn't even know I could do that, thought it was just for asking directions & stuff. I sent my first text message via Siri dictation almost 2 weeks ago, and it was very impressive. Sure beats pecking out messages, whether on a physical or virtual keyboard.

    SxyDrkHair saidArt Deco, there is any different? Does it go faster or the same?

    I haven't noticed any change in speed. It was the 4G icon that got my attention. And I wonder why Apple had that icon in waiting there, on a phone I got back in November?
