when you restore again phone starts working(but it is not a logical solution)

Hi All,

After long waiting with a dead iPhone, now apple did some good update for network issue that we are facing.. I hope it will work for everyone as it worked for me..

Follow the following steps:

1. Back up your user content and settings using iTunes or iCloud. See this article for more information.
2. Restore your iPhone 4S using iTunes.
3. After the process is complete, restore your user content and settings from your backup.
4. To confirm that you've successfully restored, verify that the version is now iOS 5.0.1 (9A406) in Settings > General > About.

Please let me know how you are going with it..

Cheers

i have restored my 4s to 5.0.1 (9A406) but there has been no change!! i dont get the invalim sim or no sim options but i cant make a call or send a sms!!

In my case it as well did not help - signal stability is even worse than with 9A405 version And in my case I still get Invalid SIM message - interesting is that it happens always overnight (not sure if there is any timeout).

i wish my fone works flawlessly:/ i am gonna try some other network now!!

I did talk to Apple Support few moments ago, they explained to me that it would be better to replace my iPhone by a provider where I bough my phone unless I want to wait for a new firmware upgrade. I explained to them that this is difficult as I did purchase my phone in a different country and based on this I asked more questions about this issue.  Those were the answers:

• If I would get my phone replaced the guy on support told me not to upgrade to 5.0.1.
• I was told that they think (but he couldn't confirm that) that it is not a hardware issue
• Firmware 5.1. should resolve this

I decided to wait for 5.1. - I cannot use my phone at all till then which is really a pain and I wish Apple provides to us at least some kind of discount or kind of appreciations that we survived without our phones for so long.  If this issue wouldn't be fixed in 5.1. I will completely move from Apple platform because this is not how you handle customers when you buy a phone for 700 USD.  Frankly? How should I handle a scenario when I would be a witness of an accident and would need to call emergency? Do I need to wait till my phone gets restarted?

Hi Rudy;

making restore everyday solves the problem till the next day 5.0.1 (9A406) doesn't solve the problem.

Also changing the phone with a new one is not a good solution beceause they also come with 5.0.1

Is there a clue about the release of 5.1

Regards

Hi Uralcan,

They unfortunately were not able to tell me that.  I did ask the support guy, than the technician I was able to get to talk about the problem but I was told that they as well don't know {Support} till its officialy released to public.  I tried as well to ask if I can test the beta to provide them feedback if that fixes that issue but that as well can't be done unless you pay that 99USD developers fee.

Thus - I just switched back to BlackBerry and will wait till they release 5.1

Hello. I have final explanation of this problem... I communicate with Czech Apple technician section and now I know where is problem. All phones with IMEI beginning with 0129 have this problem, phones with 0130 doesn't. I have changed 4 phones with apple store and now I can confirm that when I upgrade to iOS 5.0.1 on phone with IMEI 0130 I have no problem with my SIM. Older ones make problems with signal dropping, searching, invalid SIM etc. So if you can, change your phone as soon as possible for newer version.

I have the 0130 imei and I still have this problem! I've tried everything I saw on this topic and it's the same. My problem is that my phone is purchased from US and I live in Romania and I can't change it here. My second problem is that when I tap the phone on the lower back (not where is the camera) I feel a smal vibration like something is lose in there. I have an iPhone 4S 32gb.

Ok Flaxos, now i´m scared...

My iPhone has the 0129 IMEI just like you wrote. The most important question is:

Will Apple make a recall of these affected phones? Will Apple solve this with a firmware update???

Thank you so much flaxos, that's really an important update at least lets us know the affected ones before buying and unboxing them. I am in Iraq and using (Zain IQ) carrier and I faced the same **** problem with the iPhone 4s  . . and I didn't get one till now. I'll work on your advice regarding this issue . . . again thank you.

the problem is i have already upgraded mine o 5.0.1! and i cant return it and get a new one as well! coz i bought it from UK and i am currently in pakistan!! and i dont know what can be done now!! i am also waiting for 5.1! i hope it fixes the problem:/

I have 0129 - interesting, if I am not mistaken reason they mentioned that they release a new version of this iOS wasn't because of our network issue but to support upgrades of new phones released last week by additional providers.

But how come that people were not seeing this issue with 5.0? Will wait for 5.1 - if that doesnt help than I will replace it in a shop like you mentioned.

Thanks for that info,

Rudy
