So my dad upgraded to an iPhone 4 and gave me his old 3G. I was planning to just tinker around with it, but it will not connect to WiFi. It searches and finds the SSID's just fine, but times out when it tries to connect.
I'm running 4.2.1 stock on it, and I even tried JB it to see if that would help. No luck. So is this a hardware issue? Is it something that can even be fixed?
