Ever since I replaced my 7730L Jetpack with the 8800L Jetpack I've been unable to obtain data usage on the devices itself -- it always responds "Data usage info is not available at this time". I can see there is a software update available for the 8800L, but the device responds it is unable to download the update. Is there any way to 1) force a software update or 2) re-initiate the device so the Verizon network correctly handles these administrative functions? Network access for normal data transfers seems to operate normally -- except for occasional re-connections.
