SAM Unlock method for iPhone 4 and iPhone 4S?

What is SAM?

I didn't have experience with iphone unlocking via SAM.
But Recently i unlocked my network locked iphone 4s by Remote unlocking method with a help of http://www.unlocking4u.com/apple-iphone-4s/rs5wp9/. Here i unlocked my iphone 4s without jailbreaking at low cost. If you are interested in this way of unlocking try this one. They provide unlocking service for iphone 4 also.
