If you're planning on selling your Samsung Galaxy S2, you will want to reset it to its factory settings. If your phone is no longer working well, a reset may help to address that.

When you reset the Samsung Galaxy S2, it will erase all of the data on the phone, and, if you choose to do so, any data stored on the internal SD card. This includes any downloaded applications, application settings and data, and it will remove any Google account associated with the device. It won't delete the current phone operating system, the bundled system applications, and any data you have on an external SD card.
