as you know, phones are expensive and have a bazillion features. the emulation of them provides people with a chance to try before they buy kinda thing.
the second thing you're talking about is achieved by downloading logo manager (or similar program off downloads.com) and its appropriate crack/patch (off kazaa).... then you gotta buy either a data cable (specific to the phone) or infra-red cable if the phone has infra-red thingy. using data cables makes SIM card management easier and you can directly put logos, pic msgs, ringtones and SMS texts onto your phone via PC
