Hey Elize, to uninstall apps or games off the Smart Tab 3G navigate to Settings > Apps > All or Downloaded > scroll through and locate the app or game you wish to uninstall by name and tap it > tap Uninstall > and confirm ... wait for a while until the uninstalling is completed. No you can not use Bluetooth to send apps/games or from the tab but you can use an app called "Share It" - you can download the same app from Google Play Store.
