Verizon's website was frank yesterday "Badly". Despite all the CEO, who guaranteed the stability of the company at all levels during the start of sales of the updated iPhone 4, everything turned out as always. To order the ill-fated smartphone, the operator’s customers had to update the website at best dozens of times, and the number of various errors in the operation of servers exceeded all reasonable limits. They mocked their competitors, but they themselves turned out to be no better.
And at 4 a.m. Moscow time a surprise appeared on the Verizon website: SOLD OUT!
However, this horror does not concern you and me. But the device itself is of considerable interest to all of us: Apple contributed to its design positive changes. And we're not just talking about the antenna.
The largest Western media received their test smartphones a week before the start of sales. The day before, they all almost simultaneously burst out with a whole series of reviews of the gadget, through which the same idea was visible. This idea is as old as time and relates more to the realities of life than to one poor phone: the ideal is unattainable.
What will the new iPhone please its future owners who have eaten their hands up to their elbows trying to order a “handset”? The most important advantage: now using iGadget you can truly talk with anyone within New York and other densely populated American cities. Previously, the AT&T operator, unable to cope with the incredible loads on its networks, regularly “cut off” calls from ordinary people with alarmingly frequent frequency. This fact, to put it mildly, upset operator customers who own a locked iPhone.
Something like this
AT&T sure takes a lot of sh*t today
Now all this is in the past. Verizon Delivers Unparalleled Quality voice communication compared to its competitor. None of the test calls (lasting up to 40 minutes) were dropped due to technical problems on the part of the operator. This would simply not be possible on AT&T. Verizon coverage tighter, and due to this, the iPhone 4 in the new edition picks up a signal from everywhere and with a large “margin”. Is it worth curtailing the agreement with the former exclusive distributor of iPhone in the US for this? Everything is already here not this way obviously.
The fact is that compared to AT&T, the speed mobile internet at Verizon below competitors' values are on average two to three times. Pay attention to test measurements from two phones on different networks:
Moreover, the features of CDMA technology doom users of the updated iPhone to use the network in only one direction: either the Internet or calls. Both actions are impossible at the same time: the 3G connection will be disconnected by the incoming call, which is not good. And that's not it. According to the latest data, Verizon is ready limit traffic 5 percent of customers who use the Internet more actively than others.
There are slight differences in the appearance of the device. The antenna now consists of four equally spaced segments, which looks nice in terms of symmetry and overall unity of design. It's strange, but back panel The device has also changed a little: from it logos removed certifications, and the text was subjected to tracking before it was compacted into a rectangle shape:
Some felt that the display had been improved a bit. However, these may only be production costs. And now an obviously unpleasant detail: as we did before, the access point mode drains the battery smartphone for... 4 hours. There is some tar in the ointment.
It turns out that there is real parity of offers on the US market. If you need to make a lot of calls and talk on the phone, the best choice- Verizon. If the smartphone will be used for permanent exits on the Network, you still can’t find anything better than AT&T. Almost two identical smartphones two have absolutely different operators. Time will tell who will emerge victorious. Users and Apple has already"skim off the cream." [wired & engadget & nyt & techcrunch ]
P.S.: iPhone unlock 4 with a CDMA module turned out to be a daunting task beyond what is permitted under US law. So yes, even don't get your hopes up.
The good old tradition continues... Engineers from the iFixit portal team when they get their hands on any new Apple gadget They admire it for about five minutes, and then they pick up a set of screwdrivers with an industrial hair dryer to boot, after which they begin to disassemble the device down to the last component. During disassembly, as a rule, new interesting details are discovered, which are then used in tables like ours.
On February 7, 2011, the CDMA modification of the iPhone 4 was subjected to merciless unscrewing. Interesting news attached :)
Everyone has long known that the CDMA-iPhone differs in appearance from the usual GSM version. The device has a different antenna, in which the sections are located differently, and is completely devoid of a SIM card slot. But internal differences are also significant. Notice the completely different shape motherboard(microcircuit that fits around the battery). On the left is an iPhone 4 CDMA, on the right is an old iPhone 4:
This is what the motherboards look like when taken out (on top is the CDMA version, on the bottom is the old iPhone 4):
In the CDMA-iPhone, a different brand of flash memory is immediately noticeable (Toshiba instead of Samsung). But the main difference is modem chip. The CDMA version of iPhone 4 is installed Qualcomm MDM6600 chip- the same as Motorola Droid. The most interesting thing is that this chip supports two different communication standards at once - both CDMA and GSM . But in the iPhone 4 CDMA, the GSM modem functions are initially locked, and even if they could be unlocked, the lack of a SIM card slot initially makes the idea useless.
In other news, it should be noted completely new vibration motor in CDMA-iPhone (in the photo below it is on top). The motor vibrates a little stronger and a little more intense:
Apple has prepared an unpleasant surprise for iPhone repair services. It would seem that the displays in old iPhone 4 and him new modification completely identical. But that was not the case, because they are attached in completely different ways:
To summarize, we can say that the iPhone 4 CDMA in terms of hardware is noticeably different from last year's iPhone 4; moreover, based on the CDMA-iPhone hardware, you can confidently make predictions about the iPhone 5. For example, there is no doubt that the new iPhone models, which will be presented in the summer, a universal modem chip from Qualcomm will appear. What else will Apple surprise us with this summer?

iPhone 4 CDMA, what is it?
I will try to give a detailed answer to this question!
Recently, the so-called iPhone 4 CDMA. Many people have no idea what it is. And these are real friends iPhone 4 identical regular iPhone 4 only you cannot insert a SIM card into it. You can flash it for a CDMA operator and use it as regular phone.
I hasten to assure you that this is not a copy, and not Chinese fake, this is one of the varieties of iPhone, except for the difference in the SIM slot, it is no different.
Do you know what's most interesting? New like this iPhone It's much cheaper than the one with a SIM card. Its cost in Ukraine is approximately $300 “wow” really? But even more interesting, this is used iPhone CDMA, in Ukraine it will cost about $150-180, it’s just tough, isn’t it? Taking into account the fact that Americans treat things much more carefully than we do, used ones are sold in very close to ideal condition.
The only cost beyond the cost of the iPhone is connecting to the operator's network. There is now a very popular telecom operator in Ukraine Intertelecom. The one-time connection cost will cost you no more than 500 UAH. with approximately 80 UAH remaining in the account.
And so I’ll tell you in more detail why I recommend buy iPhone 4 CDMA.
1) iPhone 4 CDMA is quite cheap, given the fact that in terms of its capabilities and characteristics it is much superior to newer smartphones.
2) Connecting to Intertelecom you get a bunch of bonuses and interesting tariffs:
Subscription fee 30 UAH per month
-2 phone numbers, mobile 094 ... .. .. and landline (057)780 .. .. (THIS IS IN ONE DEVICE) call the landline call will be from (057)780 .. .. call mobile call will be from 094 ... .. .. !
-for 30 UAH per month you get 150 megabytes of high-speed Internet daily (the Internet is really fast, and EVERY DAY :))
-for 30 UAH per month you get 500 minutes per month for calls to local landline numbers
- further tariffs: to local city numbers 0.10 kopecks if you spoke for 500 minutes, to numbers in the region 0.45 kopecks, to numbers throughout Ukraine 0.55 kopecks, to any mobile operators 0.55 kopecks, calls to fixed numbers Russia 0.25 kopecks, calls to numbers mobile operators Russia 0.25 kopecks
3) Covering Intertelecom very extensive, and you can call or go online anywhere without any problems.
4) And the most important thing for me is constant access to the Internet, I correspond on Skype and ICQ, wherever I am, I call via the Internet on Skype or Viber, I can read my mail and respond to it everywhere, I use my organizer everywhere, which is synchronized with the computer, so I can set myself some kind of task that I, for example, came up with while standing in a traffic jam, and when I arrived home, I do this task I’ll see it on my computer, in general, for this money I can’t imagine anything more advantageous offer.
5) The speed and quality of the Internet is much better than UTEL or MTC.
You can buy such an iPhone in many stores in Ukraine, in Kharkov for example our friends sell them AVIC online store. As far as I know on this moment They even give a good discount if you order an iPhone 4 CDMA and a connection to Intertelecom together.
And so to summarize, in order for you to receive this miracle, with all its benefits, you need:
Buy an iPhone 4 CDMA somewhere, then go to an Intertelecom store and connect to an operator.
-Buy iPhone 4 CDMA in the AVIC online store, and immediately order the CDMA operator firmware into it, and get another discount on all this. Connecting to the operator takes approximately several days.
You see how everything turns out to be much simpler than it would seem. But for so little money you get a very functional, modern gadget available everywhere!
