Tethering
Tethered Mode allows your computer to obtain an external data connection by using the device’s wireless data services and a wired USB connection. Tap USB tethering to activate tethering mode.
Important: If you are using your device for Tethering, you may be prompted for additional drivers. The Samsung Mobile Driver for SPH-D710 contains the ADB, CDMA, & WiMAX drivers that are required for using either Tethering (Phone as a Modem) or development tools.
Go to SAMSUNG and visit the D710 Product page, where you can navigate to the Download Center to obtain this driver.
The online FAQ also provide detailed information about this driver.
A wireless data connection can be done by using the device’s Sprint Hotspot feature.
Certain data services requests may require additional time to process. While your device is loading the requested service, the touchscreen or QWERTY keyboard may appear unresponsive when in fact they are functioning properly. Allow the device some time to process your data usage request.
Make sure the microSD card is installed before you use the camera or camcorder. All pictures or videos that you capture using your device are stored on the microSD card.
If you are not satisfied with an application, you can ask for a refund within 24 hours of the purchase.
Yup good one. I hadn't heard about that. I'll stay in the camp of "skeptical" on this for now though, given the other inaccuracies in the manual.
