A friend of mine switched from an verizon iphone 4s to a Droid and gave me his old iphone 4s for verizon.  I would like to switch this iphone to Straight Talk but do not want to interfere with his contract now.  How do i go about getting this new iphone unlocked so that i can put a straight talk sim in the Iphone 4s?  I am new to this and any help would be extremely useful. Thanks.
