a lot of iphone users that have the same problem here send back their iphone to the apple....but if the phone that bought is from outside malaysia then i think that u need to find someone that can change the wifi chip..u can ask crxr ( http://forum.lowyat.net/index.php?showtopic=920182&hl= ) (can repair iphone 2g ,3g or 3gs)...have been dealing with him for quite sometime now. Try to pm him

users that have problem with their wifi connectivity need to test within a few difference wifi connection...try it at starbuck @ ur home wifi@office wifi or hotel wifi. give it a try...if still not working try to reset all setting...or restore ur phone back or upgrade or downgrade ur firmware which do u think ur wifi working for the last time. If not this case has turn into hardware failure...advise given by other forumers that users need to send the iphone to the provider such as MAXIS and SINGTEL....if not users can have other option that is repair with lyn forumer that provided services for repairing iphone.

my friend iphone got stuck with this problem yesterday....iphone can detect wifi but cannot join the network....not only at public wifi but also at my home and his home.....have been doing all the thing that i have list down before....even i have restore his phone to fw3.0 but still with detect but not connected wifi network. now i have assume the problem are hardware.
