Ask your new cellular provider.
Most will be able to port your number from the old provider.
If it's the same provider, ask them - 99% they'll keep your old number.
I kept mine when switching from prepaid to a postpaid plan with the subsidized iphone3gs (they even gave me a new free SIM that I had to activate pretty soon since the old one had some glitches on 3g in some places).
CAUTION (if you already had a gsm/pcs/dcs/3g cellphone): the iphone4 uses a smaller SIM card than other cellphones or older iphones. Most companies will replace it for free, or you can chop the old one. Make sure to write down the serial numbers on the old SIM, then back up the phonebook and SMS messages before chopping, since chopping CAN go wrong.
TL;DR Call the customer service dept of the provider you'll be using the iphone4 with and ask about phone number and SIM.
Yes as the mobile number is dictated by the sim not the handset.
It is not 'wasting' energy; it is using energy to maintain a number of functions and keep them standby for instant use. If you do not want to waste battery energy, switch off the phone completely.
Yes they have to let you keep your number now.
Yes, you CAN keep a Verizon number if you switch to AT&T! You must speak to the porting department of both companies. AT&T's porting and activation center number is 888-898-7685.
Yes you can switch and keep the same number but a fee applies and it has to be requested by the new company.
The telecom industry refers to telecommunication. The industry uses telephone calls as a revenue generator but telecom now includes images and text. Mobile phones, computers, and telephones are all connected with networks and the telecom industry helps keep everyone connected.

Telecom Management is basically a network used to deal with open systems inside of a communications network. They basically help keep the the communications interconnected and properly functioning.
The coolest IPhone accessory for the car is something to hook it up to your radio. In my experience tape deck adapter works best, but radio ones work too. IPhone cases and covers are the most fashionable accessory, you can switch it often to keep up with trends for little money.
Should have no problem. There is so much competition now, many carriers offer that to entice you to make the switch.
