Have you tried a "reset network settings"?

Did you "restore from iTunes backup?"

after upgrading to 4.3.3 I had issues with my WIFI, I did revert to 4.0.2 and had no problems. I upgraded again to 4.3.3 and the issued came back, I went to a genius at apple and I couldn't tell him my phone was ok with 4.0.2 because eh would know I j/b my phone previously. I did not mentioned anything, but I gave him as much information so he can determine what was the best case to fix the phone....they determined, faulty wifi antenna and gave me a refurbished phone. Sometimes Firmware behave differently on different phones.
