How may of us wanted to know what was inside a cell phone? For the amount of money paid for this cellphone: ($10) with no contract. Only a US passport and the green piece of paper! You can't go wrong with an electronic tinkerer wanting something to play around with.

This phone was packing an ARM processor (meant specifically for cell phones) with several other chips. The other chip must be a memory module for the processor. Nothing fancy there.

The next chips are the SKY77542 which is a transmit and receive front-end module (FEM) with an integrated Power Amplifier Control for dual-band cellular GSM900 and DCS1800, and the AD6548 which is a complete GSM.GPRS Transceiver. These do the actual cellular communihoneyions.

The next chip is the AR1010. This chip is a complete FM Radio Receiver. This can be used to receive FM radio stations between 76 - 108MHz. This was the best part of the phone =)
