My wifi antenna is broken!
When I first got my iphone 4S it was a year old handme down from my sibling and it was still under apple care. I was having problems with it's signal reception so I went into the apple store and got it replaced.
about a month after I got the replacement phone, the wifi's switch was greyed out and I tried everything i could find to fix it but nothing worked. So I brought it back into the apple store about a month later and they told me that my wifi antenna was broken and the only thing I could do was buy a new iphone for some $200 or upgrade to an iPhone 5S for $300 since I'm no longer under apple care.
Does anyone know what to do at this point? I don't have the money to buy yet another replacement and frankly I'm pretty angry that my first replacement was a faulty.
iPhone 4S, iOS 7.0.4
