Striker99,
As most people can't be bothered to read the 50 pages of posts, I'll summarise:
1. This is not a software problem. This is not an IOS problem, it's a hardware problem. It may have occurred after an upgrade, it may have occurred before an upgrade. Mine occured a long time after an upgrade.
2. Freezing it does seem to help for a short while (10-30 mins), after then it fails. I cannot recall a post where somebody has said it works permanently.
3. Heating with a hair dryer occassionally helps. Contrary to popular belief you are not reflowing the solder. My soldering iron melts solder ar around 240 degrees (depending on the mix), you can get other solder that melts at a lower temperature, but your hair dryer is not going to melt solder. Just think of the impact on your hair of a dryer that operated at that temperature. Where people say they have seen a hot air gun being used in a repair, thats to get the iPhone separated. I cannot recall a post where somebody has said it works permanently.
4. Resetting the phone in every possible way does not fix the problem. You can restore it, factory reset it, blah, blah, blah. It will not work. You may happen to get your wifi chip to work again for a while, but once it's gone, its gone.
5. Once your phone shows the symptoms of the button graying out, it will not work. Life is like that sometimes.
6. Apple does not care about you bleating. Its a large corporation and no matter what you say, it will make zero difference. Do not waste your breath, do not use capital letters, do not bother writing to them. They have made lots of money by not caring about you once their contractual obligations are gone. Why should they? For every person who goes over and buys a Samsung S4 (a better phone by the way), there are other people queuing up to buy an iPhone. Welcome to capitalism. The only way you will get Apple to listen is through legal remedy, if you think you have a case, then reach for your laywer. Fight them in the courts. Or buy a couple of percents of their stock and get yourself onto the board. That way you meet Tim Cook personally and tell him your problems. You don't like it, great, go elsewhere and vote with your wallet, works both ways, thats the beauty of the market. By the way, this is not just Apple, all organisations work like this.
There, that's saved you reading the pages and gives you an accurate summary of where we are.
