It’s great not to have to fly across the world and wait overnight in line.
The iPad 3G definitely shows some interesting differences when compared to its Wi-Fi-only sibling, mostly due to its additional 3G / GPS functionality.
- 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 (à 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.
- There’s a single GPS antenna that 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.
- Who would’ve thought: Apple uses the same 3G baseband processor in both the iPhone 3GS and the iPad 3G.
- The baseband processor in question is the Infineon 337S3754 PMB 8878 X-Gold IC. It was actually white-labeled on the production unit, but with enough sleuthing we were able to confirm its true identity.
- The iPad 3G has a Broadcom BCM4750UBG Single-Chip AGPS Solution, whereas the iPhone 3GS uses an Infineon Hammerhead II package. Big win for Broadcom!
