I have two iPhones 4s. Since upgrading software couple of days ago the phone reception is now very poor and hardly works. Keep on having to call back with no signal. This is the first time I have complained about an Apple product and am very disappointed. Are others experiencing this difficulty?

iPhone 4S, iOS 5.1.1, Phone reception

    Yes, me also. I have a Blackberry 9700 and an iPhone 4s.

    Because of poor signal in my location I have Vodafone Sure Signal which gives full 3g in my home by VPN.

    I only needed this since getting my iPhone which has always been substandard for reception compared to my BB.

    Since the 5.1.1 upgrade however I'm constantly on edge (pun intended) and I have to keep switching to airplane mode and back again to obtain full 3g on the 4s. My trusty old BB has full 3g 100% of the time.

    There is a problem!!!! Wireless reception is much worse after the update iOS 5.1.1. See this thread too:



    It is already generating a lot of angry people!!!! And I am one of them!!! Why can't Apple programmers have a decent product ... something always happening ... what is wrong with R&D department? Here is the solution, hire whole bunch of teenagers in high school or colleges, give them free phone, tell them play around with it, and tell us if anything is wrong with this phone! Call me crazy, but product needs to be up to the everyday use standard! and if it is not, no matter how great is your phone, you loose even loyal customers! And … I get that you are trying to be the innovative leader in mobile electronics department!


    I have iPhone 4S and I like it, but if this is going to continue, I might switch to something else more reliable! P.S. I’m not an Apple product person, so it is very easy for me to switch over to something else.

    Apple R&D folks, please have a fix soon!!!

    I have exactly same issue. Since upgrading to IOS 5.1.1 on my two iPhone 4S the 3G is now appalling. In fact when using my Sure Signal at home they are now unuseable. Restored devices to factory, reset network settings and even replaced my SureSignal box and it makes no difference. ThreeUK on iPad is even worse. Apple have definitely broken something. As others have said switching 3G off and on helps the situation for about 10mins then they drop off the 3G network again. Have logged the call with Apple and they are unaware of the issue. So frsutrating that I can't downgrade back to 5.1 which worked fine.

    After the recent iOS update, my phones (both 4S and 4) and , new iPad have started showing  SERIOUS Signal/reception issues. At my residence, I always used to have 'the Best' signal (with ALL 5 bars), until i did the 5.1.1 update. Since then, signals are going down to 1bar and at the max I have been getting 3bars and that too very rarely. I tried all the troubleshooting options: turn off/on cellular-data option, turn off/on airplane-mode, Wireless Network Reset, Restore from backup, Restore AS NEW Phone. (and each I have tried at least more than twice, and some of the simpler steps 10s of times). Every such troubleshooting method SEEMS to work for 5-10mins (sometimes unto 30 mins) and then BACK to 1-bar reception.  What's wrong new iOS??
