Before I went to sleep, late on Thursday evening I was checking some things on my  phone and noticed Apple had snuck into my phone with an OTA 5.0.1 update option. Because my phone had started performing some spontaneous resprings out of the blue, I thought the update may address the glitches since the update to iOS 5. 


"Cool, lets do it."  I am thinking to myself, "Tomorrow I will be rid of this iPhone nightmare"...


I awoke yesterday morning with a completely dead phone. It took me about thirty minutes to get to the point where my phone could even boot.  I let the battery completely charge then started to check everything out and maybe figure out what drained my battery.  From around 7 AM, on Friday until around 10 AM Saturday I sat before my computer, trying everything.  I only ate once, and pounded a frozen pizza before returning to my iPhone issues.  On top of the battery drain issue getting worse on the day following the 5.0.1 update, I started loosing service spontaneously.  It got to the point around 3 AM this morning that I gave up with the battery at about 75% and all radios off.  I hoped that 5.0.2 would come out by the end of the weekend the nightmare will end.  Depressed, I turned off the power to every piece of electronic technology in my bedroom. 


When I woke this morning, the first thing I did was to power up everything and keep working on the iPhone issues.  The Apple Support Communities didn't have any new fixes I could try out to just get my phone service back.  I spent about an hour of Google searching;  going over everything in my mind, hoping I could think of something novel that I will try, that no one else had.  I opened iTunes/iPhone to go through all the preferences.  My phone was connected to WIN7 computer and iTunes didn't see the phone.  After a unplug/plug-in  via USB it comes back and iTunes sees it.  This was not so unusual, but I did something next that I would have put small odds to fixing my dilemma.


I updated iTunes and it asked me to reboot my PC.  I then performed a sync for the, perhaps 150th time in two days!

Looking at the 4 bars, waited for the connection to drop to 1 bar, followed by a "No Connection".This cycle will repeat every thirty seconds if nothing changed.  I waited...


and waited...




I have had between 3 and 4 bars in the status bar for 2 and 1/2 hours now.




If your story is anything like mine, update iTunes,  reboot your computer, and synchronize your phone with iTunes.  You may get as lucky as I did.



Question:  DID updating iTunes fix your "No Service" issue?

iPhone 4, iOS 5.0.1

    What do you mean you updated iTunes? You didn't have the latest version installed? Or you did a clean install?

    Hi, it seems two things here does not apply to me,

    First is i have an iPhone 4S. So any iPhone 4s user have tried this troubleshoot, and importantly it worked ?

    Second, I am using iTunes on Windows XP, and not on Windows 7. Besides iTUnes on my XP is the most updated one. So how do i update it further. .

    I am having the same problem with my 3GS. Will this solution work too? I have tried everything else also.

  • essex-man Calculating status...

    I would love to know if this works on 3GS


    I have held back on the upgrade - because I rely on my phone so much


    Also, has anyone experienced problems with MAC OSX or is this just windows?

    Macbook, & iphone 3gs

    Updated iTunes etc. as suggested.  Still have NO SERVICE Problem and 100% at midnight was 2% DEAD at 6:30 AM with no use!! Time to head to the Apple Store to see if they have a fix. BTW this is a 0130 IMEI.


    WOW while looking for s/n and IMEI, I just happened to cleck the the Automatically Send,, Diagnostic and Usage Data. There are over 270 awdd_2011-11-19......text frames of different data. If these were all sent over my WiFi last night, that might acount for the battery drain. Also I am missing the ATT usage info I used to find in this location
