I needed to remove my battery, so I did. After I put the battery back in my
device, it powered up, but all my messages and other data were gone. Is it
all gone for good?
No, all your data is regularly saved to the Danger service so it is safe. If you wait a
few minutes, all your data will be restored to your device. (Note, however, that any
data you entered or modified between the last save to the Danger service and when
you removed the battery will be lost.)
Chances are you removed the battery before powering off your device. Every time
you power off your device, your data is saved to the device's internal flash memory.
However, if you remove your battery before shutting down, your data will not be
saved to flash. It is, however, saved on an ongoing basis to the service, which
means your data is always backed up! However, for your convenience and to avoid
unnecessary data traffic, always power off your device before removing the battery!
How can I improve radio reception when I'm in a "fringe" coverage area?
Try the following to improve radio reception:
Use the hands-free headset and position the phone away from your body.

Walk to a window if you are indoors.

Step outside of buildings that have high metal, concrete, or earthen content

because they may absorb radio signals.
Step away from metallic windows because they absorb RF energy.

Go to the highest spot possible to make the call.

Step away from computers or electronic equipment.

If you are in a car, first park, then try the call from outside the car.

If you are near or directly under a cellular/PCS radio tower, walk at least one

block away.
