iOS 6.1

[Jesstor]

I recently updated my iOS to 6.1 on my iPhone 4S and wi-fi has greyed out. Had apple store try everything and was told I must buy new phone since my warranty expired & my pink indicator shows phone exposed to humidity. I explained to no avail my phone was fine before update. Anyone with similar update issue.
Sprint iPhone 4S v6.1.2

I used to have some issues with my 4S occasionally greying out the Wifi, but a reboot would always fix it. Ended up never getting it swapped out.

Unfortunately, you might be out of luck with the moisture indicators being tripped.
