More Detailed Apple iPhone 4 Teardown Emerges

After iFixit's initial teardown carried out hours before the iPhone 4 was initially released, UBM TechInsights opened up its own iPhone 4 and carried out an even more detailed analysis of the innards of Apple's latest smartphone.

TechInsights senior analyst Steve Bitton (opens in new tab) said that the phone's 3-axis digital gyroscope may well end up in the second version of the iPad as the latter has a suitable spot next to the iPad's accelemometer.

The article confirmed what iFixit already discovered (opens in new tab), that the 3-axis accelerometer is built by STMicro and is labelled, L3G4200D, one which has yet to be released commercially to other partners.

Not surprisingly, both the iPad and the iPhone 4 share a lot of components, so much so that EETimes joked that the iPhone 4 should be rebadged as the iPad Nano. Both come with A4 processor, Samsung 256Gbit x8 Flash memory, Broadcom's all in one integrated comms die and Intel NOR Flash memory.

The obvious reasons why Apple chose to make the iPhone 4 like the iPad and vice-versa lies in the fact that the company will use the combined purchase power to negotiate cheaper prices. Also getting the same components saves development resources as programmers need to concentrate on only one platform, so to speak.

It will be interesting to find out whether the next version of the iPod Touch, scheduled to be launched on the 9th of September 2010, will be a cut down version of the iPad.
