You are confusing several technologies.
GSM phones don't have an ESN. They have an IMEI. The IMEI is the "serial number" unique to each GSM phone. CDMA phones (and most older phones on systems like AMPS) have an ESN.
If you refer to changing the IMEI in a GSM phone then no; I don't know of any current model that lets you do that, some old(er) models from Nokia and Ericsson did indeed allow it but because IMEI's are used by some networks to block stolen phones the changing of the IMEI is near impossible.
