Anyone find a solution to the reduced WiFi sensitivity issue since upgrading to 3.0? I have reset my Network setting and reset my iPhone entirely but I still have reduced WiFi. I thought 3.1 and then 3.1.2 would have fixed this but it hasn't. I should add that is has been a known issue since June and Apple has yet to address it. As I sit here in my home, my laptop can see 3 other WiFi networks beside my own. Yet my iPhone can only see mine. It used to see others, just like my laptop. Great job at screwing up a good thing Apple!
