When is the DL tablet going to get a software upgrade that will fix it from being a paperweight? I have had mine going on three months. Right after purchasing it it gets a forced spftware upgrade that will no longer allow iot to log into the DL system. So far I have gone thru 5 new tablets mailed out by AT&T. This is bull considering I paid for this device to be part of your DL system and can't use it.
