I would suggest you that unlocking an iPhone 4S using remote unlocking service is the safest and easiest way to do. You can get the remote unlocking service for an iPhone 4S from Theunlockspot.com at affordable cost with easy unlocking guide. This is a permanent unlocking method and doesn't require a jailbreak too.
To convert your regular SIM to Micro SIM you can take it to any nearby mobile store. They could do it for you. It is a very simple process.
