    I doubt you'd have a problem with a new phone, especially if you upgrade it over iTunes (I assume the problem you had was upgrading over WiFi). And now it should be under an updated warranty anyway right?

    glad you got sorted and agree with you not upgrading to iOS7!


    but surely that isn't how it should be, Apple issued the update and intended it to be used to update the 4s, so many people have had issues as a result, I acknowledge that the suggestion is that the OS update caused a latent defect in the phone to come to the surface


    I don't know whether the responsibility lies with the latent defect in the phone, or the OS update, but in my opinion there is a common denominator in both

    Hi, I have the same issue, Apple support just recomended me to replace my iPhone fo 199$ in store, as we dont have official Apple stores in Ukraine i have to send it to USA, so someone should replace it and send me back.


    ****, on one word.


    Does any one tried to roll back to iOS 6?

    Please keep in mind when updating to IOS 7 and having issues with wifi connecting that often this can occurr due to the physical wifi/router has not been updated to the most recent software that will then enable the wifi connection. Work around can be sucessful when unplugging the physical wifi router then plugging it back in. IF your iphone worked prior to the IOS 7 update and now is not working I would ask that you attempt to update the software associated with the wifi router and the internet service providing the connection.

    Good luck.

    PhilipRoy, i am interested, have read the problem description before posting? how can router influece disabled wi-fi switcher?

  • vict.shevchenko Level 1 (0 points)

    Hi, I have fixed the issue, in service center for mobile phones. it costs 50$.


    As I was told 'grey wifi switcher' is a problem of 1 from 3 iPhone 4s. And for fixing it, they make the heating(warming up) of wi-fi chip.


    I dont recomend you do it independently )))

    If you have warranity - Apple replaces such phones for free. But dont accept it as a factory defect. So better talk to specialists.

    For all those who are out of guarantee: Worked for me and saved me $200 and a lot of time.

  • Mac OS XP Level 1 (75 points)

    I have heard that that solution works. I'm really confused about what's actually happening inside the phone (and what unknown weird things the WiFi might do as a result). Tricking software? Fixing software? Fixing a burnt WiFi chip with more burning?

  • tmiskiew Level 1 (0 points)

    The downside is limited to $200. So far my phone works like a new after the hair dryer precedure.

  • cjwireman Level 1 (0 points)

    OK!!! I tried heating phone up. I left phone in in sun before. I figured it wouldnt hurt to try. After pulling it out of frezzer> It still did not work. HOWEVER.... After powering off and on phone IT WORKS>>>>>>

  • Mac OS XP Level 1 (75 points)

    I really would like to know what's happening with this fix. Is it tricking software to use a damaged piece of hardware? Or is it fixing confused software?

  • Suamir Khan Level 1 (0 points)
