ios 5.1.1 Installation issues and known bugs

No problems installing, no post-installation problems. And no problems upgrading from 4 to 5.0.

I, too, have not had any problems. You have to realize that the problems posted here are from a very few people of the thousands of people who upgrade and never have a problem. People don't post just to say everything is fine

I have been having issues with my Iphone 4 since updating. I did OTA update. I have issues when receiving calls and making calls. Party on the other end of call can not hear me. Also, the phone can hang from time to time when a call comes in. Seems to be related to the phone app and other apps on the phone being open at the same time.

The phone was working great until I loaded this last update.

Christopher,

I have an iPhone 4 also and I have been having the same issue since I updated to the IOS 5.1.1. When making or receiving calls the other person can only hear me for 5 seconds. Have you figured out how to fix the problem?

A restore did not work to fix the issue. The behavior acts like some sort of memory leak issue. The phone app gets slow, and hangs, the phone gets all out of joint, and sometimes reboots. I wish i could go back to the previous point release I had no issues with it. Anyway back to the behavior. I noticed when I make a call sometimes the speaker is highlighted, if that happens, I know the call will go through but no one will be able to hear me. If I play with the speaker key, and the mute key it eventually will work, or reboot the phone.

I really wish APPLE WOULD FIX THE ISSUE!! I hope the error is captured in the error logs that get sent to apple.

I also have noticed that when the phone is in working condition, and i open a few apps like facebook or twitter, and then go make a call, sometimes it wont work, the call goes through but no one can hear me. A hard reboot of the phone at that point fixes the issue

I reset the factory settings, I reset the network settings, I rebooted the phone, I removed the SIM card and nothing has fixed the issue! I plan on going to an apple store to see if they can help with the issue. This is very frustrating because I've never had any issues with my phone before this ios 5.1.1 update.

Yeah I had no problems with MY phone although I waited for a while to hopefully avoid problems. BUT on my wife's iphone 4, the apps are greyed out in iTunes and she is unable to make any app choices in iTunes. I rejected the iCloud but she didn't know better. I suspect this as the culprit. Also we use different computer systems for our iTunes, so this is the only ohter variable that could factor in to the cause.

STILL no fix or admission of cause found yet...
