Nope - telephone networks are increasingly digital. Calls are clearer (even over long distance), the networks are more reliable and can handle many more calls than the old analogue service ever could.
No, most of the landline telephone network and almost the entire mobile phone network use digital technology.
In terms of the history of the signal, it was the analog signal that came first. That doesn't mean that it can't still be used in conjunction with an analog signal in today's use.
There are Android 2.0 phones out currently that support the preliminary 4G networks available today. This compatibility is determined more by the phone than the operating system.

Analog televisions have been made in all sizes from 3 inches up to 37 inches and beyond. There is at least one model of 42 inch plasma television that was purely analog. Today, analog only televisions are increasingly hard to find and will not be made for very much longer.
Multi-track analog tape recording is still used today (although not commonly).
It depends on what is an 'antique phone'? If you mean the phones used in the first half of the 20th century (e.g. the phone designed by Bell), then you cannot do much with them, those phones are not compatible with the current phone lines and networks. If you mean 30-40-50 years old phones then you can make calls with them if you connect them to a phone line and you have subscription for the phone service. 20-30 years old phones may support tone mode as well, then you can use key-press controlled phone services.

Integrated circuits are produced with a myriad of functions today. Although early ICs tended to be digital logic circuits, there have been both analog and digital types throughout their history. Many ICs now combine digital and analog circuitry within a single package. So, an IC can be digital, analog or a hybrid of the two.
