I bought my wife and I iPhones Last Friday. I was able to sync up our home wifi to both phones with no problems. Last night I was down loading updates for apps over the wifi on my phone and it locked up for a short time. Then dropped the wifi and went to 3g. Since then I have not been able to connect my phone to my home wifi. My phone shows a weak signal and when I try to connect it says that it is unable to connect to network. I checked my wife's phone - no problem. Her phone has a great signal for wifi. Reset my router. Restored my iphone through itunes - still the same. At this point I am unsure what to do. Didn't know if it was a hardware or softwear problem with the phone. Any help would be great - thanks.
