In the presence of such connections and special software it is possible to edit the mobile phone address book on your computer, mobile phone address book synchronization with the data of the computer, downloading music (eg Siemens S55 You can upload files to MIDI), screensavers and logos, update phone firmware. In connection cable two disadvantages: lack of universality (different phones need different cables to connect to the computer only), and oddly enough, the high price (they have to buy separately). Much more universal connection built-in IR port (IR port, IRDA) and the radio interface Bluetooth. IR ports are more common, but do not use them very convenient, because you have to have a device at a short distance in the line of sight. It’s believed that Michael Dell sees a great future in this idea. And the speed is low.
Communication by radio and faster, and do not necessarily get the phone out of his pocket – easy! And you can buy special Bluetooth-headset – then we can talk on the phone, which is, for example, in the glove compartment of your car (and even dial phone numbers in the presence of voice dialing). Minus, as in all the good one – the lack of the prevalence of Bluetooth and a high price. What else should I look for when choosing a cell phone? Polyphonic ringtones will provide your device a unique 'voice' that you do not mix up with other people's phones calls. However, the usual pischanie phones without Polyphonic generally more shrill, and it's easier to hear – so that the function of polyphony more aesthetic than practical.
