Hi, I just got my iphone 4 for about a month now. It is running in version 4.2.1 Jailbroken All went well with my iphone on its first weeks until I experienced a problem with its Wi-Fi just this lately. I was at my friend's house and luckily he got a WiFi built in. I successfully connected my iPhone to their WiFi. The iPhone appeared to be connected to their network because I did see the WiFi curves besides my mobile carrier's name and its bars. The catch is, when I opened Cydia it said "Unable to Load The Internet Connection Appears To Be Offline." I was also unable to open any 'WiFi needed' apps like Safari, Facebook, etc. it seems the phone is not connected to any WiFi network but actually it is! My friend had an iPhone 3G and the WiFi worked perfectly fine for him. He can browse the net, open cydia, facebook - everything my iPhone 4 failed to do. That same day I went to the mall to test if I indeed have a WiFi issue with my iPhone. It did the same thing! I was able to connect to the mall's network but cannot load cydia, safari, etc. I resolved the problem temporarily when I reset my iPhone (holding home button and power button at the same time). When the iPhone started I connected again to the network and opened cydia and I was happy that my WiFi worked again. But the problem came back when I returned again to the same spot in the mall. I tried to reset the phone again but it wont work anymore. Please help!
