Prior to upgrade 3.0 using my iPhone in my house it could see numerous other WiFi networks from my neighbors. When I installed 3.0, I could only see my own home WiFi network. Since installing 3.1, it is clear this issue of weak WiFi reception has not been addressed by Apple. Are they even doing anything about it? It is sad that prior to 3.0 I could sit inside my car in my driveway and connect to my home WiFi but after 3.0 (and with 3.1), I can't even see my home network until I walk in my house. Is this really that hard of an issue to fix?
