Hope this works for you. I read another thread where someone said to go to your DNS setting on your wifi network that your phone is picking up. Delete the DNS numbers that are in there and put in an OPEN DNS number. I used 208.67.222.222 and now it works!!!!!YEAH!!
GOOD LUCK

Go to settings, wifi, and wait for your network to load. Click the blue arrow to open up network info, go down to the DNS field, delete anything that is in it and put in 208.67.222.222
There's actually two addresses that you can enter. Those are:
208.67.222.222
208.67.222.220
The only thing I found a little annoying when using OpenDNS was this: I normally quick type the url (when using my Mac) I know into the address field - missing out the .com but instead of automatically adding it instead it take you to the OpenDNS list of possible options. That's the only downside I found though.
