Black iPhone 4 16gb only £150! ?

Selling my great condition iPhone 4 16gb black as I am upgrading to iPhone 5. Phone is locked to 3 network. Home button is a little sticky, sometimes have to press it a few times to get out an app, so I have set up an onscreen home button and dropped the price to £150 for a quick sale. Phone is not blocked, jailbroken or water damaged and apart from the sticky home button and a small scrape on the bottom left of the device (not on the screen) is in good as new condition. Comes with a back cover to protect against scratches, fromt screen has no scratches or damage. Cash only, no scammers or trades. I can meet you in a coffee shop or other public place in the center of town. Any other questions please ask.
