Most of the differences are due the iPad 3G's additional 3G / GPS functionality, said iFixIt, which also noted the following highlights from its internal examination:
- The immediate visible difference is the inclusion of a black plastic RF window on top of the iPad for better antenna reception.
- The black RF window significantly changes the opening procedure. You cannot start separating the display using the notches on the top (Ã la Wi-Fi version), since that will undoubtedly break the RF window. You have to start from the right side and gingerly proceed to the top and bottom of the iPad.
- There are actually FIVE antennas in this iPad:
- Two antennas handle the cell reception — one is in the RF window on top, the other attaches to the LCD frame.
- A single GPS antenna is also housed in the RF window on top.
- Just like the iPad Wi-Fi, there are two antennas that handle Wi-Fi / Bluetooth connectivity, one in the Apple logo and another to the left of the dock connector.
New to the 3G iPad, there's an antenna attached to the backside of the display assembly.
