2 iPhone unlocking

I have a Sprint USA iphone and a AT&T USA iphone. Both are 4S. I will provide IMEI numbers and you will get me the appropriate unlock codes or whatever needs to happen to be able to use them for other carriers but specifically "LIME" or "DIGICELL" which companies are located in the Cayman Islands. There are many unlocking services out there which range from $1-$50 but I trust Freelancers way more than I do some random unlocking page. Your bid should be to have both of these unlocked. Once they are unlocked I will release funds.
