hi I'm sorry my English is poor. how i can make a unlock factory server by IMEI like this site letsunlockiphone5.com & theunlockclub.com. thnaks ---------- sorry. up post
Basically you can't. To do an unlock on the server side you need access to the server. Those companies do what they do by having someone in the inside. The best you can do is buy it unlocked, wait out your contract and ask your Carrier for an unlock or jailbreak and do it by alerting the firmware.
