no now features are unlocked. unlocking just enables you to use your phone with other operator's sim card. you cant make a CDMA phone comatible with gsm they are different frequency and different spectrumAFAIK
IMEI is the unique-id given 2 each fone...when they r developed...
unlocking means unlocking some new features such as possibility of using any
SIM Card....such as "iphone unlocked"
e.g: suppose if a hacker somehow makes a CDMA fone compatible with
any SIM card....then its called unlocking dat fone....get it...
