iOS 5.0.1 problems - Searching for Network and battery life still isnt great.

HUGE, HUGE, HUGE problem with iPhone 4s antenna with iOS5.1 that did not exist with 5.0.1 WiFi drops every 30 seconds, 4G (shmore G) worthless - will transfer 0bits of data now. Not AT&T's issue as I also have a Blackberry on the same account - works fine, no data transfer or speed problems. Gotta figure out how to go back to 5.0.1 until Apple figures this out and fixes it.

I'm using an iPhone 4 GSM model, and I find that the internet takes longer to load sometimes, and the battery life does seem a bit on the short side. But I also found out that my phone had sent an older text (about 3 days old) to someone instead of the one I just typed. This caused a lot of confusion in the conversation.

On a side not, I also don't find the new camera button on the homescreen to be a) helpful or b) attractive. It looks horrible.

I have a 3GS and I upgraded to iOS ver, 5.1 and I dont what you are talking about battery life is good so is the network try and calibrate your artsy charge to 100% hen drain to 0% try switching to AT&T it it is factory unlocked AT&T works Just fine in colorado

i notice too since i update to iso5.1 i lost my 3G network and imessage and viber it drops out alot. Whats next ipad 3 got issue imagine iphone 5 when it comes out. Apple! get your software correct and tested it be4 lauching it plz..

FACETIME and iMessage

may drain your battery.

I think I solved mine. The battery lasts way longer now. Here is what I have done.

I updated iOS 5.1 and did couple of hard boot and I had an issue with notification service. So I restored my backup. During the process, iTunes downloaded iOS 5.1 again and install it with the application I had previously. Then, I had the battery problem.

I read it somewhere that there is a bug, "waiting for activation" with Facetime and iMessage so I turned them off > on (it asks your account details) > off again. Couple of days later, I tried to turn this on and off again and it did not ask me to login the server.

It seems that the services for Facetime and iMessage kept trying to connect the server for the activation without account details and causes the battery problem.

Hope this help some people.

I live in Arkansas, USA.

My battery has died down to 55%, and I have barely text/called/searched the web. My signal is also coming & going. The 5.1 update also took the word Verizon from my screen at the top.

Since I upgraded to IOS 5.1 on Monday this week my IPhone 4S spends more time not working than working.

It is constantly searching for a network.

I did not upgrade my wife's IPhone 4S and it still works perfectly.

What are Apple going to do about this?

Any way I can go back to the previous version of IOS 5 on my 4S?

I have simular problems with my Iphone 4 16. It hasnt been working good since i updated to 5.1 about a week ago. No 3g network at all. I updated my wifes Iphone 4 with the same carrier, no problems at all. its quite annoying not being able to use the iphone for phone calls.

Apple: fix this!!!!

Loss of 3g is more than likely to be due to your APN settings being wiped during the upgrade.

You'll need to reset your Netowrk Connection and the re-enter your carrier's APN setting.

How do I find the APN settting?

***, got a new sim for iphone, paid to unlock the phone, paid for credit and constantly got no service so cant use the phone for anything more than playing games or on internet via my home wi-fi. Phone was updated to 5.1.....how can I un-update it back to the previous version, or come on Apple sort out your software!!!!

I'm not impressed with Apple so far!

For 3g to work, it needs an APN.

On the old iPhone 3, the APN can be set under the Settings / Cellular Data tab and on the iPad it is under Settings / Mobile Data.

However, on the iPhone 4 this tab is no longer available (for reasons I have been unable to fathom) and it is thus a bit harder for the user to reset.

I would first try resetting your Network Connection to see if that cures the problem = Settings / General / Reset / Reset Network Settings.

When the phone boots up it should find your network from the information stored on your SIM card.

If 3g is still missing, one way around the problem is to download a copy of the "iPhone Configuration Utility" and create a new "Configuration Profile". You'll need to connect your iPhone to your Mac via its USB cable.

Run the Configuration Utility and in the left window pane, click on Configuration profiles.

Then click on the Icon with the + symbol in the top left corner to make a new one.

Give the profile a name and scroll down to the bottom option "APN" in the right pane.

Enter the APN setting for your carrier, you can get this from your carrier, their website sometimes or google it.

Then click on "install" to send it to your iPhone. You will also need to accept it on the iPhone (follow the prompts).

That worked for me.

PS: lots of Apps on the iPhone use location services for ads (in many free games), updating info (weather & stocks etc) and tracking. If your 3g is not working, these will keep trying to connect and probably run your battery down pretty quickly. Try turning Location Services off to see if battery life improves.

I had the same problem with the network, got a brand new sim since than am not having any network issue. Whenever, I turned it off and back on again my phone goes automatically on 3g network and I have to disable manually. But, I've noticed that my facebook and email notification doesn't work nor it has any sort of sound. Also, too many dropped calls. I bought it after my galaxy s2 died after just 6 months of using it. Not happy with the 4s, my wifes 3gs has no issues at all.

If you disable the 3g works great, but I still get too many dropped calls. I've no issue with the battery, I get easily two days.

I've noticed a battery issue, also after the software update for about 3 nights at around 1a my phone acts very funny, not responding to my touches and instead acting on its own. After 4 hard restarts it finally got back to a "normal" state. I also noticed that this update said it would correct "the iPod's random stops during play." I never had this problem until the "fix" - it instead gave my phone the issues. I generally never complain but it's been such an inconvienence lately I had to ***** somewhere. Tried registering a complaint through Apple but I had to pay for a call or some crazy thing like that. Again, inconvienence in the Complaint Department.
