How to unlock my new Iphone so I can use it?

I just bought my iphone 4s off of ebay. The seller I bought it from has a 100 percent rating. I opened it up and the phone is locked? What do I do can I use it? Is there any way to restore it without knowing the pass code?

Hit up someone on Craigslist in your area. There are many that offer this service for around $40.

I would factory unlock the iPhone. I unlocked my iPhone when I went to London for school. I unlocked at http://www.iphonefort-mobile.com/ and received great service from them.

I bought an iPhone 4s last week, i was looking for a way to unlock it that i found some websites doing that, prices were so high but i finally found an unlock company doing that for just $25, i ordered the service and they unlocked my iPhone in about 24 hours with my iPhone imei number, no jailbreak, no softwares. It seems they are official apple unlockers doing unlocks through apple.
i'm writing these in mexico with my iPhone 5 in my pocket loaded with a local mexican simcard.
