iPhone 4S dropping network and data at random

Thanks for the info.

Beta 3 works without UDID and don't factory default the phone.

The battery problems seems to be fixed.

Maybe offtopic, but does anyone know if the ios 5.1 beta 3 works for Apple TV 2 without a registrered UDID?

HI there !!

Same problem on my 4s bought in Poland,

3 weeks

waiting for the 5.1 release day ....

Same thing with my 4s: impossible to call and send messages.

Lossing network at random. Its more an ipod than iphone now 😠

Phone from t-mobile poland

Hi,

Just letting you know that I took the phone to the service and that they immediately replaced it with a new one (iOS 5.0). I have it now for half a day and it works perfectly.

Hi,

this is also to else others who didn't solved the problem yet.

I tought that I solved my problem yesterday and really everything was fine after my update of iOS 5.0.1 9A406 firmware which is not offical Apple update.

In the morning when I woke up, of course I dunno when the signal was gone again but when I woke up I looked at my phone and it was no service or actualy it was sim error or something like that doesen't even matter. Anyways, it started again and again and whole day. I turned off the automatic search for network and select the carier that I use, worked well and then afte couple calls again, same ****.

I turned off the celular data which is general>network>celular data> off (anyone who is having problem with the a signal and network drop) will not be able to use e-mail account on his iPhone. So u basicly have two options: either u use phone on iPhone or use it as iPad, iPod and have e-mail account.

Anyhow this worked for me at least for now. I didn't have drop calls, bugs or anything, only once I had a really quciky network loss and it went away in a sec and signal was again five bars, now it's constant. I'm testing it, calling ppl, sending sms, using wireless and internet and etc. and everything is cool.

I'll give u some more info in time.

Someone was mentioning about 64 k and 128 k micro sim cards and bla bla, there's nothing to do with it's a software bug and try this way at least u will have your phone and making calls, writing msg...

Good luck

n1nja In the spirit of keeping things clear, you stated "iOS 5.0.1 9A406 firmware which is not offical Apple update" is in fact an official Apple update.

Is it ? If you're right then where is it, the update with 9A406 firmware ? If you were sarcastic then got ya 😉

Im leting ppl know that I still have signal didn't have any drops and yes improtmant, explenation for Celular data, this option have to be turned off because in this case you will not have any interferes from the other carirers.

Cus

No sarcasm here. iOS 5.0.1 9A406 is the last iPhone 4S update that is not in beta. Just google it, you will see.

Apparently,

we don't have the same google, as I can see on mine google search when I type iOS 5.0.1 9A406 the first website is macrumors and apple support 5th or 6th, thus please give me the link from apple site so u can proove what u're telling me !?! I'm no fool, seeing is believing...

V

The 5.0.1 9A406 is for the 4S only.

If u want it and u have already 5.0.1, put ur iPhone on itunes with the cable and press restore to get the last build.

Good Luck!

oh..... and here is ur link!

This doesen't proove anything, ok there's steps how to do it but when u restore iPhone and go to check the version u will see the 9A405 firmware and when u plug the iPhone and go to iTunes and go to update u will not have any updates. 9A406 can not be downloaded from apple site, I assume that u can see my point. Something is not right here and something stinks...

Update: still with a signal no drops exelent

It fix only the no service and the simcard error, no problem for all users.

Why should they waste people there time with a update that didn't fix anything for them?

As u can read, u have only use the restore to update to the latest build if u have those errors.

If not stay happy at 5.0.1 and update when 5.1 comes out.

This is unbelievable. I'm from Spain. I have been experiencing this problems:

- Sometimes when I am connected to a wifi network at home, when I leave home, I loose 3G network and have to enable/disable airplane mode trick to get back data connection.

-Phone automaically changes to EDGE or even GPRS when 3G signal is about 2-3 bars or even more powerful, it does at random.

But what's more frustrating!!! Since this past weekend I totally loose any data connection. No need of leaving a wifi connection or anything....it just stops working. Shows full bars and 3G signal but I can't surf the web. Sometimes I have to wait until network comes in a while because the airplane switch doesn't work now ALWAYS!!!

I'm pretty desperated....by the way I am on iOS 5.0.1 (9A406) which is supposed to fix network problems.... Battery life it's so so....

Please Apple seed a decent software update and fix this bugs!!!

New Update: fail again so even when u turn off celular data no helps, I noticed that or after some time phone start to bug and start do drop and second when u are changing location I just got up to go to the bakery to pick up some bread and I wanted to call my friend while I was walking there and bum again the same crap.

Let's see what's next...

It looks like that I everything is fine now for me , no drops no sim failure, here is what I did (dont know what accualy helped so I will write everything)

First I installed ios 5.1 beta 3 but issue was still there so I changed this settiing:

1. I enabled my sim pin

2. enabled siri raise to speak

3. in settings - General - Date and time I changed from set automatically to manual.

4. changed day and time

5. I rebooted my iphone and changed date and time back to automatic

Since then I have no issues with my phone. Only somethimes warning pops up that I lost signal with my operator but after second its gone and all is working.

Dont know if it will help you but It surely helped me. I am now without issues for 3 days
