I dunno exactly how to explain 3G....but it's like u can transmit multimedia info and stuffs to other users w/ 3G phones....n u can see their faces when u talk to users w/ a 3G phone....i just know that most of the phones now are 2G...take a look at this...
"3G system supports real-time communication service and high-rate packet-data service."
yeah i think so. i think it's to do with the new phone network 3. when in 3G you can video message people and stuff who are on 3 as well, but in 2G you can't and theres other nedia stuff you can't use either in 2G. Its all very confusing.
