My iPhone 4 is doing the same thing. My buddy is sitting here with his iPhone 4 and it will get on the WiFi, but mine keeps dumping me to 3G. Also, if I put the phone in airplane mode and turn WiFi on it will connect to the network, but if airplane mode is off, it keeps defaulting me to 3G instead of the WiFi. Any ideas or help here?
The "reset network settings" didn't work for me, but it was because mine was on the router side. That option is under Settings>General>Reset>Reset Network Settings. That said, before I reset my router, another iphone was still able to connect, and wireless laptops were still working. I wasn't sure it was my router until my wireless printer started getting a 169 ip address. A reset of my router, linksys e1000, fixed the problem.
Hope that helps
That started happening to me within the last several days. My iPhone 3Gs was getting warm and the battery was draining quickly. It was cycling wifi on and off several times a minute.
Coincidentally, I noticed that another new WiFi SSID had shown up with same full signal strength as mine -- probably an adjacent neighbor in my apartment building.
So I changed my router's wireless b/g channel from "auto" to channel 11. That resolved it. Wifi on the iPhone has returned to "steady state".
