Gingerbread 2.3.4 broke wifi! That's all I have to say. (Don't get me started on network connections, SMS and calls) I envy those of you who updated and are doing just fine. I've tried all kinds of fixes that I got from different forums, still no luck. I've sent 7 mails in 7 days to Samsung with not a single reply. Guess even they don't know how to fix it! My only solace is that I'm not alone judging by the scores of people who seem to be in the same boat as me. That Nexus and HTC are beginning to look very tempting right about now. Epic fail, Samsung. Two thumbs way down.
