iOS4 update - now iPhone now reboots during phone call

I guess you are 'deepsiphone' 😝

Thanks a lot for posting this. Anyway, I am worried if this workaround only disables the thermal alert(did mobilewatchdog 3.1.2 really run on 4.2.1?) and if iOS4 actually causes the temperature to increase on 3GS, then that might damage the phone hardware permanently if it overheated.

@ledoJ
1. Get file "mobilewatchdog" from 3.1.2 which can be found at
"System/Library/SystemConfiguration/mobilewatchdog.bundle/"

2. On your 4.2.1 iPhone using "iphone explorer"(available for windows/mac) browse to "/System/Library/SystemConfiguration/mobilewatchdog.bundle/" and replace it with "mobilewatchdog" which you got from 3.1.2 (step 1)

reboot

yes the rebooting issue can be reproduced. just keep it on a table lamp or some heat source. make sure the heat applied is to the back of your phone to the middle and is gradually increased. i shall post my logs so it will be self explanatory.

*Think I solved!*

Didn't read all posts so not sure if others have already said that...

If you _*turn notifications off*_ the phone will not reboot during calls anymore.

So the culprit may be an App or the entire notification system.

I tried turning off the Notifications and this seems to have fixed the problem for me too.

Just a pity I can't get notifications now 😟

But worth it to manage to make a call longer than 4 minutes

I never had notifications on. Double checked, but they are still turned off.

Why don't you try my fix

This isnt your fix...
You stole the idea some sites before in this thread from me.
Dont adore oneself with borrowed plumes!

well i didn't go through the entire thread. its just a coincidence that we both discovered it at different times. and may be you discovered it first. but borrowed plumes ! gimme a break. its not like you have a patient on it right. no hard feelings.

Cheers

ps:- just to confirm did this work for you too.

pps:- can you point me to where you posted the similar fix. thanks

Hey,
I had the exact same issue and I tried everything, no luck, nothing worked on these forums or anything.
In the end I went back to the apple shop and I got another phone on the warranty, this is your best bet. It is a hardware issue and apple (according to the man in the store) currently has no official fix for the issue, if you do not have warranty I'm afraid there is nothing you can do. Good luck anyway.

I'm sorry to say that none of your fixing has worked out for me. I turned the notifications off and I wasn't able to pass 4' 30''; I then tried the icehacker advices but I cannot speak any longer that 3 to 4 minutes!!! It really seems that it doesn't exist anything but going back to OS 3 ...

Had this same problem since i updated.. Everyone related to Apple that i have spoke to has denied the existence of this issue. I even printed out this thread to show the supervisor at the apple store and he pushed it away refusing to read it. My phone is out of warranty but the fact that the update caused the problem means apple should be responsible. Seems to me that this is just a scam to get everyone to buy the iphone 4. Im done with apple. Not going to waste money on electronics that wont work for more than 5 minutes without a cord attached...

Hello all,

After weeks of putting up with this issue I called Apple today. The fella sold me $99 worth of AppleCare first but then asked if I'd restored the phone, which I had back to factory defaults. But then he got me to turn the iPhone off, remove the SIM card, turn it back on, turn it off, replace the SIM and turn it back on. I have since made several calls to mobiles and land lines including one call of 15 minutes and it has not rebooted. Here's hoping it was a simple fix that did the trick!

By the way, as I am still under warranty he said they will that if this doesn't work they will post me out a new one and then I have to post in my old one.

Good luck,

Steve

Dear all,

I update from 3.1.3 to 4.2.1 and I configure my iphone as a NEW one.
I made some phone calls and it never reboots, only for one call after 25 minutes.
After this reboot I made other phone calls, each of them during about 50-55 minutes and the iphone doesn't reboot.
With 4.0-4.0.1-4.0.2-4.1 my iphone reboots after 4-5 minutes during call.
