Many companies give their employees cell phones to use while they are doing business. Alltel Wireless cell phones are used in many government offices as well in many industrial businesses.
Traditional telephones are powered by the local telephone exchange and do not need to be connected to a mains supply. Modern telephones often use a separate supply to power the additional features of telephones such as memory diallers, number displays, wireless handsets and so on. Most better designed modern telephones will allow the phone to be used as a basic telephone even when local power is lost. Cordless phones will not work when the home power is lost.
Yes, wireless power transmission is possible through technologies such as resonant inductive coupling or radio frequency energy transmission. These methods allow for the transmission of power without the need for physical cables. However, efficiency and distance limitations still exist in current implementations.
One of the phones used by Tom Cruise during the Pentagon scenes in the movie "Mission: Impossible" is visibly not plugged into anything, suggesting that it is a prop phone rather than a functional one.

No contract cell phones can be a useful purchase, as they allow one to obtain a cellular phone without being required to keep a certain service for a long period of time. In the United States, there are a few ways to obtain a cell phone without contract. One is to purchase the device unlocked, and then go to a provider and sign up for a month-to-month service. T-Mobile, a GSM provider, has given a separate option, in that a user is never constrained to a service contract in their plans.

There is no such thing as a "type of cell phone". There are different types of networks, however. The first major type is GSM. This is used by Cingular/AT&T Wireless and T-Mobile. It uses time slots to allow multiple people to use one tower. The next major type is CDMA. This is used by Verizon Wireless, Alltel, Sprint/Nextel (to an extent), and TechMaster Telecom. It uses multiple frequencies to allow multiple users. The final type is PCS. This is used by Sprint/Nextel and Verizon Wireless where CDMA is not available. Because PCS is a form of GSM, it uses multiple time slots.
