    Well I got my brand new replacement Iphone 4S yesterday.


    I set it up as a new phone to avoid any possible bug transfers, just in case, and promptly lost ALL my text messages going back over 2 years.... Everything else was there bar them... really disappointed as a lot of them were from my Dad who died last year and I had kept them... I guess it was going to happen one day....


    Anyhow, new phone, signal is good, although the sim pin is still disabled at present.  The signal bar gauge does go up and down lots despite being in a fabulous o2 area.   All good so far... apart from wish I had put on a glossy film protector again rather than anti glare which I am not keen on, but was expensive....

    My 4S was replaced 4days ago. The new 4S is working properly no problems with phone calls (no phone network drops) and no battery problems (battery charge lasts over 10 hrs now).  Sim pin is on for testing purposes (4days).

    My SIM PIN has been on  3.5 days and there  has not been any problems on phone calls on my replacement iPhone 4S (I got from  Apple on Wednesday).  HOwever, I would like to turn off this sim pin  setting  because it is not clear whether the sim pin on  -option is mandatory for higher security of   my iPhone4S  and there might be still some  bug related to iOS 5 causing undetectable drops from  3G phone network.

    Thank you antti51 for this tip.


    My new 4S has been working properly now since I turned the PIN lock off.

    No flat lines on 3G anymore, and it properly changes between 3G and GPRS. These are the options we have were I live.


    Now to wait for the IOS 5.1 update.

    Follow-up on my own post.

    For me it does not help to disable PIN..... Still have issues with that the phone looses signal completely and outgoing calls fail (in areas with good coverage).


    Hope this is a software error that will be fixed in 5.0.1!

  • pnearn Level 1 Level 1

    I have the same issue


    Disabling SIM PIN doesnt fix it. Apple support have suggested doing a restore. Do you think its worth a try or get a replacement?

  • pnearn Level 1 Level 1

    Think i may have figured it out, at least for me (and killed 2 birds with one stone re: battery life)


    The 4S now has multitasking. If you double click the home button you can see all the running apps. Holding them down shows a red minus which allows you to kill them. When I turned them all off, bar the base IOS5 apps the problem went away (same thing would happen if you restart the phone)


    So it will be a rogue app that is causing this which isnt being turned off. Guess only way to work out which one is to try them all but i havent got time


    On a side note this also increases battery life, I found i has something like 30 odd apps running so no wonder my batter was draining so fast

    I seem to have similar problem with losing 3G on a 3GS working on Orange PL network. Disabling SIM PIN doesn't work on contract SIM cards. Looks like a firmware issue to me.

  • tpero Level 1 Level 1

    Apparently I had spoken too soon before when I thought the problem had fixed itself. I resisted for a while, but finally performed a full restore and set up as a new phone (NOT FROM BACKUP). It's been a few days, and I THINK it's working. I haven't lost the 3G signal once, and the battery life has improved as well. I'll report back in a few days to confirm.


    Setting up as a new phone will force you to lose your old text messages, high scores on games, etc. I was irritated at first, but I'm over it; there are worse things in life. Assuming you have your contacts/calendars synced through an exchange server or icloud, I think there shouldn't be any problems there.

  • pnearn Level 1 Level 1

    Did you try killing all background apps?  As above?

  • zzMarecki Level 1 Level 1

    No, not yet. The problem happens occasionally so I'll try it next time I see it. Still, I don't think that's a real fix, just a temporary remedy.

  • pnearn Level 1 Level 1

    I agree but my guess is there are apps that cant/dont manage the CommCenter stuff well with multi-tasking. In which case either Apple fixes apps being able to do that or we find the apps causing the issues and report it to the vendors

  • Repairee Level 1 Level 1

    Same issue with me here in Germany. I even brought my wifes 3GS out with me to compare and the 4S drops to "No Service" while the 3GS is totally fine. Both phones on the same network.(Telkom)


    The only way to get the network back once in "No Service" is to shut it off and turn it back on again.


    So far I've tried:


    3 new SIM cards

    Resetting Network

    Resetting Phone

    Total Restore


    Now I've taken the phone back to my carrier, and they are sending me a new one. We'll see if that helps.


    So far, very dissappointed with the iPhone 4S.

  • flamman Level 1 Level 1

    Repairee: Did you try it without doing a restore from backup?


    What I mean is did you test the 4S if setting up as new device? Did you have the problem then as well? If so, I would say it is more likely a hardware error.

  • Repairee Level 1 Level 1

    I set it up as a new device. When that didn't work, Applecare told me to take it back and get a new phone. ie: hardware issue.
