iFixit has gone to work on another Apple device. They've already taken apart the iPad 3G and had a look at the innards.
Apple has managed to again arrange the insides of one of their gadgets to fit nicely in the device as can be seen by the picture below:
For comparative reasons, here are the insides of the wifi model as well:
iSmashPhone ran a super-scientific test just to see which device had the faster 3G connection, the iPad or the iPhone 3GS, which according to iFixit use the same 3G baseband processor.
Still, the iPad was faster on the network than the iPhone 3GS, but only if used without the case. Which all may be explained by the fact that the iPad contains more antennas: two for cell signal. One of which is in the small RF window on top, and one that is cleverly attached to the LCD frame, effectively creating an additional antenna.
The following are three antenna: Wifi/Bluetooth, GPS and 3G (Left to right)
Below is the iPad 3G's main board and the A4 processor:
Above, on the right, you can see the connector for the communications board.
Again, for comparative reasons, here is the wifi model's main board:
Here are closer views of the differences: (3G on the left)
And just above the A4 Chip, what iFix it figures may be a signal processor: (Again, 3G on the left)
Most of the differences are expected for a device that adds 3G connectivity. Though it takes someone with serious tools to take their iPads apart. We are having too much fun enjoying our iPad 3G from the outside. Either way, we tip our hat to iFixit for taking the time to take their iDevices apart.
