    i missed ups,so it will take a few days more to get my iphone from apple.

    here in germany a few people send there iphones to apple and get "new"phones from them also with ios4 and the reboot problem is gone.no reboots during a call.

    so for that reason i think it is a hardware problem at some 3GS phones.

    I've this problem too .,

    I got two reboots during the call with my 3GS with iOS 4.0.1 on the 10th day since updating the firmware, I do shutdown to my iPhone helps me to fix the problem, but until now - and after reading all of these comments - i doubt that reboot may accrue with me again. i didn't face this issue while i was using iOS 3.1.3 !!

    any reason or fix for this very serious issue !
    or downgrade to iOS 3.1.3 is the solution ?!

    Please Help !

    You can pray Steve (every reboot) and wait the next great update, or try http://www.techradar.com/news/phone-and-communications/mobile-phones/how-to-down grade-iphone-ios-4-to-os-3-1-3-704705

    But it seem risky.

    I think I may have accidentally found the fix for this issue:

    1- let the battery drain until you cannot exit the lock screen - iPhone will show plug in status.

    2- connect to pc with latest iTunes open and wait for the phone to connect. - iTunes told me it could not read the iPhone

    3- hold sleep + home and reboot the phone while still connected to pc.

    4- iPhone should now be read by iTunes, activate and ur done

    Phone should be stable now.
    I read some logs in this thread that suggested the issue maybe related to a return signal from the battery I can only theorize that allowing the battery to run down to nothing allows os4 to synchronize with the battery correctly.

    Can others please test this? I wrote yesterday(previous page) about my experiences and I'm going on 24hrs without an issue now. So please let ur batteries die and give this a try.

    would be worth adding some comments to this news story re the 3GS problems as well.

    I have been on this forum previously complaining about the phone cutting out and rebooting about 4 minutes into every call.. however i have just had two calls in excess of ten minutes with no problem...what has made the difference? well i did two things..i tried to upload ios4.01 (ever optimistic!) after two hours just before completion it threw up an error so failed to install.after the failure i synched the phone via itunes as usual...he other thing i did was download all my photographs (about 80) to my computer leaving my camera roll empty..now i have no idea if either of these made a difference but fingers crossed up to now the phone problem is solved....

    Another unhappy Apple customer!

    Yip ever since 4.0 my phone reboots during calls lasting between 4-7 mins. This is on a 3GS 16GB, its funny as my wife also has a 3GS 16Gb and ios4 and she has had no problems what so ever!

    Right now, I will never buy another Apple device....

    Exactly the same thing is happening to me.

    iPhone 3GS 32GB which I upgraded to iOS 4.0.1 last week (from 3.1.3 not from iOS 4.0)

    The very next day I was in a call for around 5 mins in a low-ish signal area and the call got dropped. To my amazement when I looked at the phone rather than see a "Call Failed" message I saw the Apple logo - it was rebooting itself. It took ages to reboot.

    Just now I had exactly the same things happen again.

    Each time it happens it loses any reference to the call that was dropped i.e. that call does not appear in my Recent calls list. Annoying because I wanted to call the customer back but as it was their first contact I didn't have any record of their number. They haven't called back.

    What the heck is happening? I had the occasional call drop with 3.1.3 but I NEVER had this calldrop/reboot thing before I installed iOS 4.0.1.

    Does anyone know where we stand with Apple on this? I mean, my phone is just over a year old now so what can I do? Can I still go to an Apple Store and have them look at it?

    Wish I'd read this thread before upgrading, I just wouldn't have risked it.

    Same thing happended to me. after upgrading to iOS4 Periodically phone calls gets dropped after typically 5 minutes, and the phone displays the white apple of death. Seems very consistent for incoming international calls, regardless of where I am placed relative to GSM network (at office, in airports etc). Other calls,- such as local calls I have placed myself, seems to work much better.
    Very difficult to use the product as a business phone. I have now started to say "Please could I have your phone number and other contact details. I have an iPhone and it may disconnect us any minute".
    It would be good if Apple could make just a tiny statement on this problem, just to indicate if they take it seriously - even if they do not have a solution for it right now. I know finding software bugs that are difficult to reproduce in a controlled environment, can be very difficult to nail down.

    "Curiouser and curiouser!" said Alice in iPhoneland...

    Jokes aside, at the risk of seriously tempting fate, as I type this update I've made 5+ calls since yesterday afternoon and none have resulted in a reboot. The liklihood is that now the next calls are going to trip up(!) but what did I do yesterday afternoon that's led to the current success..? Quite simply another factory restore (with no data), i.e. set-up as new iPhone.

    Looking at the contents of this thread, I find it amazing how so many people are getting mixed results when trying the various fix attempts. Personally I'm still sticking to the concept that the root cause is software and NOT a hardware fault with some 3GS models. To name but a few, some people get success by resetting network settings, some by switching off 3G, and some by removing all videos! The last one's my favourite, and whilst I see no link to the rebooting issue, if it works for some people then good for them (although not acceptable in my book!)

    I restored my 3GS again yesterday because I was a little bored. Plus, because I'd noticed that even with iOS4 (prior to the release of 4.0.1) my signal bar strength had been lowered and I wanted to see if it would get better or worse. Whether coincidance or not, what I've observed since yesterday is my 3GS seemingly handling the mobile signal better.

    Both at work and at home would have seen 3-4 '3G' bars prior to iOS4. Since installing 4.0 and 4.0.1 the bars are typically 1-2, with 3G. My guess was that the phone was determined to hang onto the 3G signal, boosting power to keep it, but which resulted in the battery working overtime and seemingly overheating, causing a reboot when no temp was reported back. My recent 5+ calls have either seen 1-2 bars 3G maintained or 3G drops and seconds later 3-5 bars of GSM (I think it's called GSM..?) Sometimes 3G would even come back.

    So, I seriously question not necessarily the iOS4 code but the success of it's installation each time. Again, isn't it odd how so many people get different results..? For me, I called AppleCare last week and have a ticket number. As soon as my 3GS reboots again then I'll be calling back to invoke a replacement iPhone. In the meantime, Apple still need to acknowledge this major fault.

    But for now, maybe, just maybe I have a fully working phone again...

    Well, Alice in iPhoneland is not yet available... http://alice-in-wonderland-books.com



    UPS picked up my iPhone last week; it went from Ireland to Germany to the UK, it seems. Got clocked in at 07:30 on Friday, and the replacement was evidently sent out at 09:30 the same day. Today is a bank holiday in Ireland so no deliveries: I hope to have my replacement (new? refurb?) tomorrow if not Wednesday.

    Am in the meantime using a Nokia 3210 and it is excruciating...

    Well I thought my iPhone was fixed but i've developed a different problem.

    Just before work I was playing minigolf/reading BBC news app. I clicked the top button as I was about to start work then put it in my locker. When I came back it was dead to the world. I've plugged it into iTunes, it recognises the phone, but iTunes says it couldn't connect as there was an invalid response from the device. At no point can I make the phone light up or do anything.

    Booked in to local Apple shop tomorrow...

    So just to summarise. It seems the best idea is to take the phone back to where you got it to get a new one? Sell it on eBay get a Blackberry and forget the whole nasty iPhone thing ever happened?

    The sad thing is that I resisted all things Apple for years... stuck with PCs and Nokia phones. I finally buy an iPhone because everyone in the whole world is raving about them, and because I wanted a phone with a good music player. iPod and a phone in one - and such raving reviews, what could be better? And then it does this.

    So, to add my name to the list: 32GB iPhone 3GS, worked fine for the short while I had it before updating to 4.0. Now reboots during calls almost every call, not at any other time.

    I'm a business user and, as well as the reboot thing, I have also had people tell me that my phone has been engaged or unavailable when it hasn't. So who knows how many business opportunities I might have missed. I've resorted to paying for a multisim service so I can keep my trusty old Nokia N91 on - at least that will ring if this rotten Apple is playing up.

    Also extra annoyed that Sonera in Finland tell me that if I send it for service there's a waiting list of 3 weeks, and I have to send it before I get on that list - so I have to be without the phone, paying for it and the data package etc. all the time, for at least 3 weeks before they even start to look at the problem. That's why I'm on this forum, hoping to find a fix I can sort out myself; but it seems that Apple have absolutely useless customer support as so many people have the same issue and they remain silent on the matter. And I haven't got all day to sift through forums, I've got work to do!!!

    So back to Nokia it is then, and a fight with Sonera for some recompense...
