    The mechanical concept of the S35i differs in various points from the one of the other Siemens mobile telephones. The first thing you will experience is how the housing is locked. In S35i no screws are used to keep the housing closed. Also inside the telephone no screws are used anymore. To open the housing, which is kept closed by catches only, a special opening tool has been defined.

    Hardware Description The handset consists of the following major integrated circuits: 1) E-GOLD (PMB 2850) This IC is a combination of microprocessor and signal processor. The microprocessor part of this component is responsible for controlling the keyboard, SIM- Card, Flash and RAM. Furthermore it controls the power up/power down of the RF module and sets the amplification of the PA.
