My iphone 4 is unlocked, it is running ios4. I live in an apartment block which has wifi. i am subscribed to this wifi on my macbook pro and it works fine. my iphone 4 sees the network and lets me 'connect' but then it doesnt bring up the screen even when i open safari to enter my user name and password so i can log on to my account. therefore i cannot use the internet through wifi. it says im not connected. i have tried resetting network settings and forgetting the network etc. it did work once many moons ago but now its is fecked. please help my before my phone gets launched through the 10th story window. cheers
