You can call it Disassembling (or) Teardown (or) opening an iPhone, or what ever you like.

The iPhoine 3G which does not have a battery panel like that in the 2nd Generation phone has a battery built in the panel.

The beauty had to stipped naked and the parts be exposed to see what this masterpiece was made up of and what makes it such a  gadget.

Fixit.com which i recently came across have been doing their teardown thing from a long time on all the new gadgets coming into the market from time to time.

These people tore down the iPhone 3G in 29 steps including their great efforts in getting hold of the 3G firsthand in Newzeland from step n.o 1 to 7, from step number 11 we can see the actual opening up of the 3G.

I could make out that the iPhone is made of parts made by many companies like Philips screws, Samsung Processor , Toshiba flash,Intel flash, Marvel for the bluetooth and wifi.

On the whole i can say that there has been a good contribution from many companies in making this beauty with brains become reality.

Apple has made many changes to make the 3G easy for repair.
