Hey guys, I bought a used 3g and everything seems to work perfectly well except that it doesn't detect wifi. I've tried just about everything e.g. reseting network settings, airplane mode on and off, reseting all settings, restoring via iTunes, etc. Long story short as you can probably guess non of these things worked. To make it clear, its not that I can't connect to a specific network, its just that the phone doesn't detect any networks (there should be atleast 4 options at my house alone from mine and my neighbors). My question is this, is there anything else I can do short of replacing the wifi antenna from inside the phone? My last resort is to try to replace it and risk breaking it, but is this worth the risk? I should have an extra one laying around from an iPhone that I took apart previously (and broke coincidentally). Some help/ reassurance/ a good tutorial would be appreciated. Thanks in advance! P.S. no it doesn't have warranty anymore...if only.
