Jan Zdarsa As we already wrote in the very first article, Apple is working on fixing signal problems. Now it looks like the new iOS 4.0.1 could appear early next week, possibly as early as Monday.
Apple employees confirmed on their forum that Apple is working to fix the issues with a signal and the new iOS 4.0.1 could appear at the beginning of the week, probably as soon as Monday. But some time later, these Apple support responses were deleted. So it is not clear if the release is being pushed back, if the employees wrote nonsense, or if Apple does not want to comment on the issue in this way.
Signal indicator
Displaying the current signal on your phone is always a pain. A great answer was given in the discussions on Jablíčkář by reader -mb-, who said: "The Elmag field is really a bit more complicated than being described by the bars on the signal status indicator, which are just a funny attempt at visualization to give people something to look at." to watch". As it turns out, although iOS 4 shows fewer signal bars than the iPhone 3GS with the older iPhone OS, calls from iOS 4 are just as good, if not better.
Bad frequency calibration in the baseband
From the looks of it, the problem is with the baseband and the problem should be that the radio frequencies are miscalibrated. The call drops seem to come when the phone should be trying to change frequency. Instead of going to the frequency where the ratio of signal strength to interference is best, it prefers to report "No service" and drop the call.
iOS 4 brought several changes to how the baseband chooses which frequency to use. Even this can be a sign that the error is mainly software and there was simply an error while editing. This explains why iPhone 3GS owners are having the same problem.
iPhone 4 has better signal reception than older models
On the contrary, signal reception should be even better in iPhone 4 than in older models, exactly as Steve Jobs said at the keynote. The New York Times did write about signal problems, but they were more based on Gizmodo articles. At the end of the article, the author writes that with older iPhone models he had no chance to call from home, while with the new iPhone 4 he already called from home for three hours in one day.
Demonstrating the signal problems on Youtube was graded, so everyone tried to hold their iPhone 4 as tightly as possible to cover the antenna as much as possible and the dashes would disappear. Then people started to cover the antennas on other phones as well (for example the Nexus One) and surprisingly the dashes disappeared too! :)
Lesson learned: If you cover the antenna of your wireless device, the signal will drop. But should this drop be so significant that there should be dropouts when the user is holding the phone normally? Rather not, and Apple should debug this in the new baseband version, i.e. iOS 4.0.1. But these problems will logically persist in areas with a very poor signal.
Jako best post to this hysteria, I refer to the tweet of the editor of AppleInsider (@danieleran): “iPhone 4 antenna blocking kills signal reception. Blocking the microphone kills the voice, and it's impossible to see the Retina display when the screen is covered.”

Why should it be difficult to describe a signal, what about the signal strength [dBm] and the "number of dashes" depends on that, I think that's quite accurate, the reader's reaction -mb- is laughable :)
Do you think measuring only by signal strength is accurate? :)
Well, it's probably logical that when the antennas overlap or what happens there, that the gain on the antenna will be smaller, surely the falling lines are not just arbitrary animation.
Otherwise, ad the other phones - I believe that the signal can be dropped in the others as -mb- wrote, but the problem is that it is almost impossible to do this when holding it normally during a call. With the iPhone 4, thanks to the antenna in the sides, there is simply no other option than to hold it by the antennas, and how many people will probably think about how to hold the phone correctly when they receive a call? :)
Holding the phone is a problem in general - for example the Nokia E72 has the antenna at the bottom of the phone and I've actually read (I think directly in the user manual) that you need to hold the phone so that the bottom is not covered ie to hold beyond the upper edges.
The iPhone 3G/3GS potentially already has a holding problem (of a completely different kind) - on the bottom is the microphone (on the right side and the speaker (on the left). I have a couple of friends with huge hands who can block the microphone while on the phone and then it is not audible, but it will probably not be a problem to block the microphone with your finger on any other phone.
So - I can imagine that under certain conditions the problem of connecting the gsm and wifi antenna can be a finger. I think that Apple had to take this into account and placed the gaps between the antennas like this on purpose (they are not in some geometric centers), but someone's finger will still come out there during a phone call - they will have to be careful or they will return the iPhone and buy a phone , which will suit him. Maybe an iOS4 update will come out that will somehow get around the problem, but it can't be completely removed because physics has to work :-)
Just out of interest - what signal strength are we talking about here? About what the phone receives? Or about what the phone is broadcasting? Interfering with the signal to others will affect it how?
Really, it's probably time to accept that the 5 dashes are just a bonus realtime game to shorten the long autumn evenings.
But it's really a bit more complicated with the GSM cellular network, because each phone measures the received power level of up to 6 cells at the same time and switches to the one that's best for it at the moment. And in this function, as written in the article, there is apparently a bug in iOS 4.0.
Does anyone remember how long it took to fix the WiFi problems with the arrival of OS 3.0?
Otherwise, it seems to me like another advertisement .. negative.. also rekama :D
a) If Gizmodo hadn't stolen (?) the phone of the technician tuning the baseband, maybe everything would work as it should :)
b) We are not threatened by this problem in our Bananaistan, even if it were sold here, the number of pieces would be in tens not hundreds of thousands per day like in the USA. By the time it is with us, the problem will be over, either with a minor FW update or a minor HW update
The Internet has a huge power in that all it takes is a unit of disaffected people publishing on a readable server and the avalanche starts... I think this problem will be solved satisfactorily.
It is currently the best device of its kind and no antenna will change that.
"best" is a rather special term. however, for me it is at least comparable to the Galaxy S from Samsung. no flame.
The best subjectively, I don't deny it :)

This kind of phone call would probably be recommended to us by the apple maker...
It is a fact that when I came home to the north, with os4 there is a weaker signal even on 3G, but it's just a subjective feeling...
When I have the full number of charms, I don't see the call.... when I have one, it looks like this... So sorry, but that indicator makes sense and to trivialize it is an alibism...
