My on/off button on top of the 3GS fell off due to a crack on the phone. Does this part come individually or do I need to purchase the front or back replacement.

Yup, you can buy it individually right here and the install instructions can be found here. I apologize if you couldn’t find it through navigating the site, I’ll fix that today.

My lock button fell off my phone. And I loved my lock button. My phone also dies a lot. So is there any way to lock my screen without buying anything
