Should I trade my iPad 2 for an unlocked iPhone 4s 16GB?

Someone has made me an offer but I'm not sure on what to do. Help me out please The iPhone is brand new out the box…

I would be very careful. Be sure to inspect everything first before committing to anything. Personally I wouldn't do it as there would be no clue what kind of technical issues the phone is having

Don't do it, wtf. An ipad costs way more, and it's so easy to unlock a phone. Not to mention, once a phone is unlocked, you can't take it to the apple store anymore or get updates.
