iPhone 4S dropping network and data at random

Hi,

I've been using an iPhone 4 on a Vodafone contract for the past 16 month and just bought an iPhone 4S direct from Apple. It arrived on Friday morning and I got it set up correctly as far as I can tell.

When I first turn it on, it works lovely and exactly as I would expect, able to make calls, send texts and access the internet via the cellular network. However, at what appears to be random, the network will disappear (no bars of signal) stopping me making calls and texts, but still allowing me to access the internet. Sometimes, the Internet goes, but I can still make calls and texts. Other times, everything is gone and I get "No Signal" where it normally says Vodafone UK.

So when trying to fix this problem after it's noticed, I try putting it into Airplane mode and back out. The phone scans for a network and goes back to the same state as before I tried this fix. I have tried resetting network settings, but this doesn't change anything. The only thing that actually fixes it temporarily is turning the phone right off and back on again.

At this stage I assume this is a bug with the software, but I wondered if anyone else is experiencing anything like this? If no one is, I will take it up with Apple, but I don't really want to do that as I love the new phone so much!!

Cheers, Stuart

1 week after 9a406 update, everything works fine. Before: lost signal, reception error, lost call...

I'm dying to know what the software problem was. What is the main problem?

There are people where the restore to version 9A406 did help to fix those issues which we all face here - but to majority still not. I've decided today to restore back to version 9A405, as at least in my case, the network faults are not that frequent as with 9A406.

Thank you Apple that you ignore our loud calls here and that we cannot use our iPhones as phones - its super cool to reboot our phones every time you want to call someone from your family on a Christmas Eve just to ask them how they are and wish Merry Christmas 😢

Merry Christmas to everyone!

Now I'm afraid to update or do anything to it. I get sim error message every morning. My iPhone 4S is pre installed with 5.0.1. I get drop call mostly when I'm driving. I think when switching antenna. Apple what are you doing? I have posted like 20 massages on yr bug report page.

I recomend to all of you to try to contact Apple. Maybe using email, Express lane or something like that...

I know they are working on it, but I believe that the real solution isn´t so simple. Someone told here that we are about 1 or 2% of 4S sales..., maybe because a lot of carrier in the world are using a modern "3G ready" SIM card. How can a 2% make great noise?

Dear Apple,

Here We are, your customers calling for you...

Maybe some of us have sleep on the door of your stores, or missed all day in a line just to buy this amazing new phone;

Maybe for some us buy this phone WAS like a dream come true;

Maybe some of us bought the first Apple product;

Maybe some of us are loyal Apple costumers;

Maybe our friends buy your products because of us;

Maybe we will do it again with iPhone 5;

...but please, Do not leave us alone!!!

(Just tell us: We know your problem, still working on it..., the fix is coming...)
