Wi Fi and 3G
If you do purchase an iPad with 3G, you will not need home wireless internet. But you can also connect to a home wireless internet with an iPad with 3G. You will need to pay monthly for the AT&T 3G fees.
No.
just activate it
The iPad accesses the web via its Wi-Fi or 3G connection (if you have a 3G model).
Ipad or Ipad WIFI can access WiFi network ( like Ipod touch) where as IPad 3g has SIM card slot and can access internet where WiFi networks are not available ( you require Data Plan from AT&T in US) for Ipad 3G if you want to access internet where WiFi network is not available. What happens if you cancel the monthly payment on the Ipad 3g, does it still work?
In the related links you'll find a picture of an iPad with two things circled; the 3G sensor at the top and the number of GB. If your iPad has a 3G sensor then it is a WiFi + 3G iPad and if it doesn't then it's just a WiFi iPad. Also it shows the number of GB.
No. Only the iPad 2 has FaceTime.
No, you cannot. The iPad requires different hardware which enables it to receive a 3G signal from your carrier. The wi-fi model of the iPad does not have the black piece on the top of the back. the black piece is what receives the signal.
