Apple IPhone 16GB Locked to 3 network !

Good condition iPhone 4 16gb locked to 3 network. Few minor casual scuff marks on the outer rim of the phone not affecting screen on working condition. Only problem is the home button is faulty sometimes has its own mind when wants to work, but is a magic button on touch screen what you can activate if any home button/volume button/lock button does not work. Willing to SWAP for Samsung S2 or S3 or make me an offer on swaps or price.
