Dear dickkhead uhi nepali, first read the comment properly before you post any other comment and if you cannot read, go and take ESL class and come back. I told pepsi how to unlock the iphone via customer service of sprint. The reason i know that is not only because my friends suggested me to do it but also i work for Sprint you shittthead.. Later i accepted on what rahasya said because i didn't know about that and i haven't tried that yet. The two phones that i unlocked was sent to Nepal and both of them are working great. The reason i haven't tried that here is because most of my friends and families in U.S. have Sprint because they are in my employee referal plan. Hope you understood now dickkkkhead.
