Hi!

I have a problem on my iphone 3GS and iPad2 for DNS connectivity.
I have read to many comments about changing DNS to 8.8.8.8. It was worked with FaceTime and push notification. But, it doesn't work for Appstore and Facebook apps (stuck in loading page). I have to switch DNS back to 192.168.1.1, then they can be connected again. Now, I have to switch between two DNS. I don't know what's the cause because everyone can use 8.8.8.8 with all apps.
My router is D-link DSL-2640T (already forward port) and Itunes is up to date.

Please help me, if you can figure it, you are gorgious...
Thank u very much....
