Enable 3G On/Off = Switch between 3G and EDGE ("2G").

Cellular/Mobile Data = No data connection via cellular. voice is unaffected. (So if a user goes to a different country, they can stop all data connections including the ones initiated by background processes, or come home to a giant data usage bill which is generally billed per kb).

Airplane mode = no radios at all (bluetooth/cellular/wifi)

ok so how come i can have a data connection on and 3G off? whats that running through ? as i can still browse internet ? this is all with wi-fi off by teh way.

im just confused as mobile data internet is faster then my 3G ?

Yes cellular or mobile data is 2g or edge. on iphone 1 you could not talk and surf at the same time. 2g uses your mobile connection, 3g is a different connection.

in pre iphone 4 that setting said "Edge Data"

"2G", which is what you are using if you have data connection on and 3G off, shouldn't be faster.
What method did you use to come to that conclusion?

BTW, the user is given the option to turn 3G data off because one can get more battery life from using a 2G connection where appropriate.

hmm. makes sence thanks. but how come you cant use 3G without mobile data being on ? (if it is only 2G) surely u wouldnt need both on?

The term "mobile data" includes both 2g (edge) and 3g connections. If you turn off 3g you'll be on edge. If you turn off "mobile data" then your phone will not connect to 2g or 3g. You would still be able to make phone calls of course.
