Let me sum up my observations in this discussion.
Everyone having a problem in this discussion has the following problem:
- All phone affected are IPhone 4s
- All problems occured after the upgrade to iOS7
- The issue we are experiencing is a greyed out WiFI button, which was not greyed out before.
- We have tried all options advised by Apple to resolve this issue.
- we are all unable to solve this problem ourselves constructively, although some of us have managed adhoc 'fixes' like hairdryers or using the fridge to 'cool off' the wifi chip.
- Our iPhone 4s's were operating without any noticable problems prior to the upgrade to iOS7
The above makes me to draw the following conclusion:
There is a clear pattern and these are obviously not individual cases. It appears the wifi chip of the iPhone 4s is being of a substandard quality and not being not fully compatible with the new iOS firmware which causes this problem. Also most of the beta testing over the past months was done using the iPhone 5 and not the iPhone 4 or iPhone 4s. Mostlikely because the 4 series were not part of the large scale testing Apple was not fully aware of this accelerated issue with the Wifi chip (when you do a Google search on "iPhone greyed out wifi" you see that this issue is not new, and you see the issue involves mostly the 4s ) But it seems iOS 7 pushed these weak and thus unreliable wifi chips just over the edge, causing them to overheat and thus to stop functioning alltogether.
Apple must be fully aware of this issue by now but they are incredibly silent in communicating with their in my estimation 'multiple thousands' of customers worldwide experiencing this problem. Apple only sticks by claiming the upgrade to iOS7 is "at your own risk" (that's what I was told) and sticking to the warranty period
(I bought my iPhone in Aug 2012, so am out of Apple warranty)
I feel that Apple should take their responsibility and help her customers in solving this quality issue.
As customers in good faith we bought this product (I paid some €600) having trust in Apple and in the faith the quality would be such that we could use it -with good care of course- for at least 2, 3 or even 4 years.
But unknown to her trusting consumers Apple created a product using a faulty wifi chip (hence the overheating issues which can eventually lead to failure)
As result of this us, we, customers are now stuck with an unusuable iPhone for which we paid plenty of money.
( One thing I am sure of, if Apple would be a car manufacturer or an airplane manufacturer they would never get away with this, and would be forced to do a recall)
My message to Apple:
It is now time to act. Taking responsiblilty never hurts (even if you for some reason feel you are not fully to blame) It gives you credit. And credit gives you loyal customers.
