who have problems after ios5.0.1 updated?

Same problem here in Brazil. Bought my 4S - 32gb unlocked in Switzerland and couldnt make it work after upgrading to 5.0.1 . Any solution? Have somebody tried to reset to factory settings (using the phone) ? I´ve heard that helped one user...

I have exactly the same problem. I thought the place I stayed did not have receptions. I then went back home, where i am supposed to get very strong signals, and still gave me SIM failure.

APPLE MUST FIX THIS ASAP. ALSO, I DON'T KNOW WHETHER THEY FIX THE ECHO PROBLEM!!!

I am a long time Apple person and we are an Apple family. NOW...I HATE this stupid IOS 5 Update!!! After it, everything went down hill. I have soooo many problems with it that I wish I could just go back ! HELP!!!!!

Sorry I've been looking around and have found no practical way of going back to previous iOS. Jail breaking might give you options but I've never tried it.

I think I am the only one here who is pleased with 5.0.1,after the update,my battery inproved a lot,I can stay with 3 or 4% of battery almost a day.

I am also getting the "Call Failed" error repeatidly in my new iPhone 4S. It is really annoying when an important call fails due to that. Apple please do something about it.

Hi to everyone. I have the same problem of sim error. I can't call nobody and I can receive 1-2 calls during 7 days. I'm waiting for some improvements with 5.02 software or I'll be forced to change my actual telephone company to a better one.

After iOS5.0.1 my battery is draining at rates of 25% per hour. Initially I thought that adding my social media apps to the default notifications screen drains the battery, so I took that out. Then I started blaming other notiifcations. Next to chop off were ALL location services.

After that iCloud went on the chopping block - no online backups or any other benefit that comes with that coud computing platform. Even Find My Iphone is rurned off.

So my mobile device is not longer modile. I have to be connected to a charger several times a day. It's pretty much a brick, a zombie, none of the apps have any of those dynamic features that would notify you about online activity. Google maps does not know where I am. An YET STILL i'm seing the same BATTERY DRAIN that started soon after my iOS5.0.1 upgrage.

If you upgrade to iOS5.0.1 you are risking being attached to your charger every 3.5 hours.

I also get the failed call and have to reboot. also notice that it is running hotter than before... charging overnite will reach full charge then shut off charging and be drained completely in morning... Have turned off apps that were not a problem prior to the upgrade. Hurry and throw something out there that makes it worse not better what ever happend to troubleshooting all scnarios prior to releasing software... where is the quality control.. out the window with percieved savings????

I'm from the philippines and i got my iphone 4s last nov. 17. It was working perfectly fine except for the battery life. The next day nov 18, I updated my software (5.0.1). After the update, I'm getting a "SIM failure" error, My network status is always No service and the battery issue wasn't fixed after the update. I hope apple will release a new software update ASAP... I want a working phone... i bought an iphone not an itouch 😟

I had the same problems with mobile connections and invalid SIM messages.

After contacting my operator they changed the SIM card in it - I'm not sure if they changed from a SIM to a USIM or the other way around - but what ever... it has solved the problem.

No more dropped connections. I would suggest contacting your operators and find out what card your on.

Hope this helps someone.

Same problem here in Brazil on TIM carrier.

I have the same problem here in Malaysia. Please do something to fix these problem! 😠😠😠

****!! I am having really weird issues after the update when I get a incoming msg my flash goes off ... And my app store is right outta wack my phone will reboot itself and I cannot play any games lik I use to I've had no issues before this 5.0.1 update and right now I'm soo frustrated!!! I hope these issues are fixed fast!

Got the "Sim Failed" problem too. Battery drained at a rate of 15% an hour.

For me the worst is the sudden SIM failure and this bug isn't even acknowleged by Apple.
