Some iPad apps such as FaceTime iMessage ..etc. require knowin other iPad users in order to use them properly so why aren't there any iPad social website to chat and get to know other iPad users
When FaceTime was new, Apple had a toll free number you could make calls to, just to test the app. I think it went to one of their Apple Stores. I wonder if it still exists.
Here is a 2010 article with the number. I suppose you could try it. Best to wait for U.S. business hours.
